Refactor MakerPoints configuration and depth handling

- Renamed `band0To10MinDepth` to `filterMinDepth` in `config.ts` for clarity.
- Updated `MakerPointsEngine` to utilize the new `filterMinDepth` for depth checks across all bands.
- Introduced a method to track depth status changes, enhancing order placement logic based on market depth.
- Improved logging for depth-related order skips to provide clearer insights into trading decisions.

+### StandX
+
+* [StandX Maker Points Strategy Guide](docs/standx/maker-points-guide.md)
+
+The strategy requires a StandX API Token and signing private key to place orders.
+

+1. Open the StandX official API creation page: https://standx.com/user/session
+2. Connect your wallet and log in
+3. Click the **"Generate API Token"** button
+4. The page will display the following information:
+   - **Token** (JWT string starting with `eyJ`) → Fill in `STANDX_TOKEN`
+   - **Ed25519 Private Key** (Base58 format, like `HdsyJD7oWgT...`) → Fill in `STANDX_REQUEST_PRIVATE_KEY`
+   - **Creation date** and **Validity days** → Used to configure token expiry reminders
+
+> The Ed25519 Private Key is an auto-generated signing key used only for trade request signatures. Your assets remain in your main wallet and are completely safe.
+
+Please keep these credentials safe and do not share them with anyone.
+
+**Configuration steps:**
+1. Set `EXCHANGE=standx`.
+2. Provide `STANDX_TOKEN` (JWT token for perps API).
+3. Provide `STANDX_REQUEST_PRIVATE_KEY` (Ed25519 signing private key, Base58 format).
+4. Set `STANDX_SYMBOL` (defaults to `BTC-USD`) and align `PRICE_TICK` / `QTY_STEP`.
+5. Recommended: configure token expiry settings:
+   - `STANDX_TOKEN_CREATE_DATE` (creation date, format `YYYY-MM-DD`)

+- Keep at least 50-100 USDT in the account before deploying a live strategy.
 - Configure leverage on the exchange manually (~50x is recommended); the bot will not change it.
 - Ensure your server or workstation clock is in sync to avoid signature errors.

+## StandX Perps Authentication
+
+官网创建的 API 提供了
+
+API Token 以及 Ed25519 Private Key，用于签名交易。
+
+⚠️ This document is under construction.
+
+This document explains how to obtain JWT access tokens for the StandX Perps API through wallet signatures.
+
+## Prerequisites
+
+- Valid wallet address and corresponding private key
+- Development environment with `ed25519` algorithm support
+
+## Authentication Flow
+
+### 1\. Prepare Wallet and Temporary ed25519 Key Pair
+
+1. **Prepare Wallet**: Ensure you have a blockchain wallet with its address and private key.
+2. **Generate Temporary ed25519 Key Pair and `requestId`**
+
+### 2\. Get Signature Data
+
+Request signature data from the server:
+
+> **Note**: Code examples provided below are for reference purposes only and demonstrate the general implementation approach. Adapt them to your specific production environment.
+
+#### Using curl
+
+```
+curl 'https://api.standx.com/v1/offchain/prepare-signin?chain=<chain>' \
+  -H 'Content-Type: application/json' \
+  --data-raw '{
+    "address": "<your_wallet_address>",
+    "requestId": "<base58_encoded_public_key>"
+  }'
+```
+
+#### TypeScript/ES6 Implementation Reference
+
+#### Request Parameters
+
+| Parameter | Type | Required | Description |
+| --- | --- | --- | --- |
+| chain | string | Yes | Blockchain network: `bsc` or `solana` |
+| address | string | Yes | Wallet address |
+| requestId | string | Yes | Base58-encoded ed25519 public key from step 1 |
+
+#### Success Response
+
+```
+{
+  "success": true,
+  "signedData": "eyJhbGciOiJFUzI1NiIsInR5cCI6IkpXVCJ9..."
+}
+```
+
+### 3\. Parse and Verify Signature Data
+
+`signedData` is a JWT string that must be verified using StandX’s public key.
+
+#### Get Verification Public Key
+
+```
+# Using curl
+curl 'https://api.standx.com/v1/offchain/certs'
+```
+
+#### Example signedData Payload
+
+### 4\. Sign the Message
+
+Sign `payload.message` with your wallet private key to generate the `signature`.
+
+#### BSC (EVM) Implementation Reference
+
+```
+import { ethers } from "ethers";
+ 
+const provider = new ethers.JsonRpcProvider(
+  "https://bsc-dataseed.binance.org/"
+);
+const privateKey = "<your_wallet_private_key>"; // Keep secure; use environment variables
+const wallet = new ethers.Wallet(privateKey, provider);
+ 
+// Sign using the message from the parsed payload
+const signature = await wallet.signMessage(payload.message);
+```
+
+#### Solana Implementation Reference
+
+```
+import bs58 from "bs58";
+import { ed25519 } from "@noble/curves/ed25519";
+import { Keypair } from "@solana/web3.js";
+ 
+const privateKey = "<your_base58_encoded_private_key>"; // Keep secure; use environment variables
+const walletKeypair = Keypair.fromSecretKey(bs58.decode(privateKey));
+ 
+// Sign using the message from the parsed payload
+const messageBytes = new TextEncoder().encode(payload.message);
+const signatureBytes = ed25519.sign(
+  messageBytes,
+  walletKeypair.secretKey.slice(0, 32) // First 32 bytes are the private key
+);
+ 
+// Solana requires a specific signature format
+const signature = Buffer.from(
+  JSON.stringify({
+    input: payload,
+    output: {
+      signedMessage: Array.from(messageBytes),
+      signature: Array.from(signatureBytes),
+      account: {
+        publicKey: Array.from(walletKeypair.publicKey.toBytes()),
+      },
+    },
+  })
+).toString("base64");
+```
+
+### 5\. Get Access Token
+
+Submit the `signature` and original `signedData` to the login endpoint.
+
+**Optional Parameter:**
+
+- `expiresSeconds` (number): Token expiration time in seconds. Defaults to `604800` (7 days) if not specified. This controls how long the JWT access token remains valid before requiring re-authentication.
+
+> **Security Note**: For security best practices, avoid setting excessively long expiration times. Shorter token lifetimes reduce the risk of unauthorized access if a token is compromised. Consider your security requirements when configuring this value.
+
+#### Using curl
+
+#### TypeScript/ES6 Implementation Reference
+
+#### Success Response
+
+```
+{
+  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
+  "address": "0x...",
+  "alias": "user123",
+  "chain": "bsc",
+  "perpsAlpha": true
+}
+```
+
+### 6\. Use Access Token
+
+Use the obtained `token` for subsequent API requests by adding `Authorization: Bearer <token>` to the request headers.
+
+## Body Signature Flow
+
+### Basic Flow
+
+1. Prepare a key pair
+2. Build message: `{version},{id},{timestamp},{payload}`
+3. Sign with private key
+4. Base64 encode signature
+5. Attach signature to request headers
+
+```
+{
+    ...
+    "authorization": "Bearer <token>",
+    "x-request-sign-version": "v1",
+    "x-request-id": "uuid",
+    "x-request-timestamp": "timestamp",
+    "x-request-signature": "signature",
+    ...
+}
+```
+
+### Code example (only for reference):
+
+```
+import { ed25519 } from "@noble/curves/ed25519";
+import { base58 } from "@scure/base";
+import { v4 as uuidv4 } from "uuid";

+ 
+  // Sign message with Ed25519 private key
+  const messageBytes = Buffer.from(signMsg, "utf-8");
+  const signature = ed25519.sign(messageBytes, signingKey);
+ 
+  // Base64 encode the signature
+  return Buffer.from(signature).toString("base64");
+}
+ 
+// --- Example Usage ---

+// Generate Ed25519 key pair
+const privateKey = ed25519.utils.randomSecretKey();
+const publicKey = ed25519.getPublicKey(privateKey);
+ 
+// Generate requestId (base58-encoded public key)
+const requestId = base58.encode(publicKey);
+ 
+// Prepare request parameters
+const xRequestVersion = "v1";
+const xRequestId = uuidv4();
+const xRequestTimestamp = Date.now();
+ 
+const payloadDict = {
+  user_id: 12345,
+  data: "some important information",
+};
+const payloadStr = JSON.stringify(payloadDict);
+ 
+// Generate signature

+
+## Key Points
+
+1. **Wallet Setup**: Uses `ethers.js` to create a wallet from a private key
+2. **Message Signing**: EVM wallets sign the message directly using `wallet.signMessage()`
+3. **Signature Format**: The signature is returned as-is from the wallet (hex string)
+
+## Environment Variables
+
+Create a `.env` file with:
+
+```
+WALLET_PRIVATE_KEY=your_private_key_here
+```
+
+> **Security Note**: Never commit private keys to version control. Use environment variables or secure key management solutions.

+```
+
+## Key Points
+
+1. **Wallet Setup**: Uses `@solana/web3.js` Keypair with a base58-encoded private key
+2. **Message Signing**: Uses `@noble/curves/ed25519` for Ed25519 signing with `walletKeypair.secretKey.slice(0, 32)` (first 32 bytes are the private key)
+3. **Signature Format**: Solana requires a specific JSON structure containing:
+	- `input`: The original payload from the server
+	- `output.signedMessage`: The message bytes as an array
+	- `output.signature`: The signature bytes as an array
+	- `output.account.publicKey`: The wallet’s public key bytes as an array
+	This JSON is then base64-encoded before being sent to the server.
+
+## Signature Format Explanation
+
+Unlike EVM wallets that return a simple hex signature, Solana authentication requires a structured response:
+
+```
+{
+  input: payload,           // Original SignedData from server
+  output: {
+    signedMessage: [...],   // Message bytes as number array
+    signature: [...],       // Ed25519 signature bytes as number array
+    account: {
+      publicKey: [...]      // Wallet public key bytes as number array
+    }
+  }
+}
+```
+
+This format allows the server to verify both the signature and the signing account.
+
+## Environment Variables
+
+Create a `.env` file with:
+
+```
+SOLANA_PRIVATE_KEY=your_base58_encoded_private_key_here
+```
+
+> **Security Note**: Never commit private keys to version control. Use environment variables or secure key management solutions.

+## StandX Perps HTTP API List
+
+⚠️ This document is under construction.
+
+## API Overview
+
+### Base URL
+
+```
+https://perps.standx.com
+```
+
+### Authentication
+
+All endpoints except **public endpoints** require JWT authentication. Include the JWT token in the `Authorization` header:
+
+```
+Authorization: Bearer <your_jwt_token>
+```
+
+**Token Validity**: 7 days
+
+#### Body Signature
+
+Some endpoints require body signature. Add the following headers to signed requests:
+
+```
+x-request-sign-version: v1
+x-request-id: <random_string>
+x-request-timestamp: <timestamp_in_milliseconds>
+x-request-signature: <your_body_signature>
+```
+
+See [Authentication Guide](https://docs.standx.com/standx-api/perps-auth) for implementation details.
+
+#### Session ID
+
+For `new_order` and `cancel_order` requests, you will want to know the results of these requests after actual matching. To obtain these results, you need to add the following information to the header in these interface requests:
+
+```
+x-session-id: <your_custom_session_id>
+```
+
+Note that this session\_id needs to be consistent with the session\_id used in your ws-client.
+
+### Request Format
+
+- **`int` parameters** (e.g., timestamp) are expected as JSON integers, not strings
+- **`decimal` parameters** (e.g., price) are expected as JSON strings, not floats
+
+## Trade Endpoints
+
+### Create New Order
+
+`POST /api/new_order`
+
+**Note**: A successful response indicates the order was submitted, not necessarily executed. Some orders (e.g., ALO) may be rejected during matching if conditions are not met. Subscribe to [Order Response Stream](https://docs.standx.com/standx-api/perps-ws#order-response-stream) for real-time execution status.
+
+To receive order updates via [Order Response Stream](https://docs.standx.com/standx-api/perps-ws#order-response-stream), add the `x-session-id` header to your request. This session\_id must be consistent with the session\_id used in your ws-client.

+# StandX 做市积分策略使用教程（超详细新手版）
+
+本教程会 **手把手** 教你如何运行 StandX 做市积分策略。每一步都有详细说明，按顺序操作即可。
+
+---
+
+## 第一步：安装 Bun（运行环境）
+
+本项目需要 Bun 才能运行。
+
+### macOS / Linux 用户：
+打开终端，复制粘贴以下命令后按回车：
+```bash
+curl -fsSL https://bun.sh/install | bash
+```
+
+### Windows 用户：
+打开 PowerShell，复制粘贴以下命令后按回车：
+```powershell
+powershell -c "irm bun.sh/install.ps1 | iex"
+```
+
+安装完成后，**关闭终端，重新打开一个新的终端窗口**，然后输入：
+```bash
+bun -v
+```
+如果显示版本号（如 `1.2.x`），说明安装成功。
+
+---
+
+## 第二步：下载项目并安装依赖
+
+```bash
+git clone https://github.com/discountry/ritmex-bot.git
+cd ritmex-bot
+bun install
+```
+
+---
+
+## 第三步：获取 StandX API Token（最重要的一步）
+
+> ⚠️ **这一步是 90% 新手卡住的地方，请仔细阅读！**

+> ⚠️ **这一步是 90% 新手卡住的地方，请仔细阅读！**
+
+策略需要两样东西才能帮你下单：
+1. **TOKEN**（API 令牌）
+2. **代理钱包私钥**（用于签名交易）
+
+### 获取步骤（图文说明）：
+
+#### 3.1 打开 StandX 官方 API 创建页面
+
+在浏览器打开这个网址：
+```
+https://standx.com/user/session
+```
+
+> **现在可以直接在 StandX 官网创建 API Token 了！**
+
+#### 3.2 连接你的钱包并登录
+
+如果还没登录，先连接钱包并登录你的 StandX 账户。
+
+#### 3.3 生成 API Token
+
+点击页面上的 **"Generate API Token"** 按钮。
+
+你会看到类似这样的信息：
+- **Token**（很长一串以 eyJ 开头的字符串）
+- **Ed25519 Private Key**（Base58 格式的私钥，类似 `HdsyJD7oWgT756124j3taSPGv...`）
+- **创建日期**（例如：2026-01-15）
+- **有效期天数**（例如：30 天）
+
+> 🔴 **请把这些值复制保存下来！**

+> 🔴 **请把这些值复制保存下来！**
+
+### 什么是 Ed25519 Private Key？
+
+- 这是系统 **自动为你生成** 的一个 Ed25519 签名私钥
+- 它 **只用于签名交易请求**，不存放你的资金

+## 第四步：配置环境变量
+
+在项目根目录创建一个 `.env` 文件（如果已存在就修改它）。
+
+### 4.1 创建/编辑 .env 文件
+
+**macOS / Linux：**
+```bash
+nano .env
+```
+
+**Windows：**
+用记事本打开项目文件夹，新建一个文本文件，命名为 `.env`（注意前面有个点）
+
+### 4.2 填入以下内容

+
+# ===== 挂单档位开关 =====
+MAKER_POINTS_BAND_0_10=true
+MAKER_POINTS_BAND_10_30=true

+- 创建日期: `2026-01-15`
+- 有效期: `30` 天
+
+那么你的 `.env` 应该这样写：
+
+```bash
+EXCHANGE=standx

+## 第五步：启动策略
+
+### 普通启动（看实时仪表盘）
+```bash
+bun run index.ts --strategy maker-points --exchange standx
+```
+
+### 后台运行（推荐长期挂机）
+```bash
+bun run pm2:start:maker-points
+```
+

+
+## 配置参数说明
+
+| 参数 | 含义 | 新手建议 |
+|------|------|----------|
+| `STANDX_TOKEN` | API 令牌 | 必填，从第三步获取 |
+| `STANDX_REQUEST_PRIVATE_KEY` | 代理钱包私钥 | 必填，从第三步获取 |
+| `STANDX_SYMBOL` | 交易品种 | 默认 `BTC-USD` |
+| `MAKER_POINTS_ORDER_AMOUNT` | 每笔挂单数量 | 建议 `0.01` 起步 |
+| `MAKER_POINTS_CLOSE_THRESHOLD` | 持仓达到多少开始平仓 | 设为 `0` 表示不自动平仓 |
+| `MAKER_POINTS_STOP_LOSS_USD` | 亏损多少美元强制平仓 | 设为 `0` 表示关闭止损 |
+| `MAKER_POINTS_BAND_*` | 三个挂单档位的开关 | 全部 `true` 即可 |
+| `STANDX_TOKEN_CREATE_DATE` | Token 创建日期 | 推荐配置，格式 YYYY-MM-DD |
+| `STANDX_TOKEN_VALIDITY_DAYS` | Token 有效期天数 | 推荐配置，与创建日期配合使用 |
+| `TELEGRAM_BOT_TOKEN` | Telegram 机器人 Token | 可选，用于接收通知 |
+| `TELEGRAM_CHAT_ID` | Telegram 聊天 ID | 可选，配合 Bot Token 使用 |
+| `TELEGRAM_ACCOUNT_LABEL` | Telegram 通知账户标签 | 可选，用于区分多个账户 |
+
+### Token 过期时间配置详解
+
+`STANDX_TOKEN_CREATE_DATE` 和 `STANDX_TOKEN_VALIDITY_DAYS` 用于设置 Token 的过期时间。配置后，策略会：
+
+1. **Token 过期前 1 小时**：在日志中提醒你 Token 即将过期
+2. **Token 过期后**：
+   - 如果有持仓：进入**平仓模式**，只允许平仓和止损，不再开新仓
+   - 如果无持仓但有挂单：**自动取消所有挂单**
+   - 如果无持仓无挂单：进入**静默模式**，只接收数据，不下单
+
+**推荐配置方式（创建日期 + 有效期天数）：**
+
+在 StandX 官网生成 API Token 时，页面会显示创建日期和有效期天数，直接填入即可：
+
+```bash
+# 创建日期（格式：YYYY-MM-DD）
+STANDX_TOKEN_CREATE_DATE=2026-01-15
+# 有效期天数
+STANDX_TOKEN_VALIDITY_DAYS=30
+```
+
+**示例计算：**
+- 创建日期：2026-01-15
+- 有效期：30 天
+- 过期时间：2025-02-14 00:00:00 UTC
+
+**兼容旧版配置（直接指定过期时间戳）：**
+
+如果你之前使用的是 `STANDX_TOKEN_EXPIRY`，仍然可以继续使用：
+
+```bash
+# 方式1：使用时间戳（秒）
+STANDX_TOKEN_EXPIRY=1735689600
+
+# 方式2：使用 ISO 日期字符串
+STANDX_TOKEN_EXPIRY=2025-01-01T00:00:00Z
+```
+
+> 💡 **提示**：推荐使用新的创建日期 + 有效期天数方式，更直观易懂。
+
+### Telegram 通知配置详解
+
+配置 Telegram 通知后，策略会在以下情况发送通知：
+
+- 📝 **订单成交**：挂单被成交时
+- 📈 **开仓**：持仓从 0 变为非 0 时
+- 📉 **平仓**：持仓从非 0 变为 0 时
+- 🛑 **止损触发**：触发止损平仓时
+- ⏰ **Token 过期**：Token 过期时
+
+**配置步骤：**
+
+1. **创建 Telegram 机器人**：
+   - 在 Telegram 搜索 `@BotFather`
+   - 发送 `/newbot` 命令
+   - 按提示设置机器人名称和用户名
+   - 获取 Bot Token（格式类似：`123456789:ABCdefGHIjklMNOpqrsTUVwxyz`）
+
+2. **获取你的 Chat ID**：
+   - 在 Telegram 搜索 `@userinfobot`
+   - 发送任意消息
+   - 机器人会返回你的 Chat ID（一串数字，例如：`123456789`）
+
+3. **配置环境变量**：
+   ```bash
+   TELEGRAM_BOT_TOKEN=123456789:ABCdefGHIjklMNOpqrsTUVwxyz
+   TELEGRAM_CHAT_ID=123456789
+   TELEGRAM_ACCOUNT_LABEL=我的账户（可选）
+   ```
+
+4. **测试通知**：
+   - 启动策略后，如果配置正确，会在 Token 过期或重要事件时收到通知
+   - 如果收不到通知，检查 Bot Token 和 Chat ID 是否正确
+
+> 💡 **提示**：`TELEGRAM_ACCOUNT_LABEL` 是可选的，如果你有多个账户在运行策略，可以用这个标签区分不同账户的通知。

+## 常见问题
+
+### Q：报错说 Token 无效怎么办？
+
+重新去 https://standx.com/user/session 生成新的 API Token。Token 可能过期了。
+
+### Q：Ed25519 Private Key 从哪来的？
+
+在 StandX 官网（https://standx.com/user/session）点击 "Generate API Token" 按钮时会显示。
+私钥格式为 Base58 编码（类似 `HdsyJD7oWgT756124j3taSPGv17vo5u7FafDq3vrun4f`）。
+**你不需要自己创建，系统会自动生成！**
+**你不需要自己创建，系统会自动生成！**
+**你不需要自己创建，系统会自动生成！**
+
+### Q：.env 文件放在哪？
+
+放在项目根目录，就是 `ritmex-bot` 文件夹里，和 `package.json` 同一个目录。
+
+### Q：为什么策略没有下单？
+
+1. 检查账户里有没有足够的保证金
+2. 检查 TOKEN 和私钥是否正确填写
+3. 检查 .env 文件是否保存成功
+
+### Q：担心平掉我手动开的仓位？
+
+把 `MAKER_POINTS_CLOSE_THRESHOLD` 设为 `0` 或者设置成一个比你持仓大的数字。
+
+### Q：如何知道 Token 什么时候过期？
+
+配置 `STANDX_TOKEN_CREATE_DATE`（创建日期）和 `STANDX_TOKEN_VALIDITY_DAYS`（有效期天数），策略会在 Token 过期前 1 小时提醒你。这两个值在生成 API Token 时会显示。Token 过期后，如果有持仓会进入平仓模式，只允许平仓和止损。
+
+### Q：Telegram 通知收不到怎么办？
+
+1. 检查 `TELEGRAM_BOT_TOKEN` 和 `TELEGRAM_CHAT_ID` 是否正确填写
+2. 确保没有在 Bot Token 和 Chat ID 前后加引号或空格
+3. 在 Telegram 中先给机器人发送一条消息（任意内容），然后再启动策略
+4. 检查网络连接是否正常
+

+
+## 安全提示
+
+1. **绝对不要把 TOKEN 和私钥分享给任何人！**
+2. **绝对不要把 TOKEN 和私钥分享给任何人！**
+3. **绝对不要把 TOKEN 和私钥分享给任何人！**
+
+代理钱包只用于签名，你的资产始终在你自己的主钱包里。但如果泄露了 TOKEN，别人可以用你的账户交易。

+## StandX Perps WebSocket API List
+
+The WebSocket API provides two streams: **Market Stream** for market data and user account updates, and **Order Response Stream** for asynchronous order creation responses.
+
+⚠️ This document is under construction.
+
+## Connection Management
+
+Both WebSocket streams implement the following connection management behavior:
+
+### Connection Duration Limit
+
+- **Maximum Duration**: A single WebSocket connection can be maintained for a maximum of **24 hours**
+- After 24 hours, the connection will be automatically terminated
+- Clients should implement reconnection logic to handle this gracefully
+
+### Ping/Pong Mechanism
+
+- **Server Ping Interval**: The server sends a WebSocket Ping frame every 10 seconds
+- **Client Response**: Clients must respond with a Pong frame when receiving a Ping
+- **Timeout**: If the server does not receive a Ping/Pong response within 5 minutes, the connection will be terminated with error:
+	```
+	{
+	  "code": 408,
+	  "message": "disconnecting due to not receive Pong within 5 minute period"
+	}
+	```
+
+**Note**: Most modern browsers and WebSocket libraries automatically handle ping/pong frames, so you might not need to implement this manually. However, if your environment doesn’t support automatic ping/pong handling, you can proactively send ping frames to the server. Example using the npm `ws` library:
+
+```
+import WebSocket from "ws";
+// ...
+private ws: WebSocket;
+//...
+ping(): void {
+  this.lastPingTime = Date.now();
+  this.ws.ping();
+  console.log(\`[${new Date().toISOString()}] Ping server\`);
+}
+```
+
+## Market Stream
+
+Base Endpoint: `wss://perps.standx.com/ws-stream/v1`
+
+### Available Channels
+
+```
+[
+  // public channels
+  { channel: "price", symbol: "<symbol>" },

+## Order Response Stream
+
+This WebSocket channel provides real-time order status updates for the `new order` API. Since order creation is asynchronous, this channel notifies clients about order responses, including ALO order rejections.
+
+**Base Endpoint:**`wss://perps.standx.com/ws-api/v1`
+
+### Request Structure
+
+All WebSocket requests follow this structure:
+
+**Fields:**
+
+- `session_id`: UUID that remains consistent throughout the session
+- `request_id`: Unique UUID for each request
+- `method`: Operation to perform (`auth:login`, `order:new`, `order:cancel`)
+- `header`: Required for `order:new` and `order:cancel` methods (authentication headers)
+- `params`: JSON-stringified parameters specific to the method
+
+### Methods
+
+#### auth:login
+
+Authenticate using JWT token.
+
+**Parameters:**
+
+```
+{ "token": "<jwt>" }
+```
+
+**Example Request:**
+
+#### order:new
+
+Create a new order. Parameters are the same as the HTTP API `new_order` payload.
+
+#### order:cancel
+
+Cancel an existing order. Parameters are the same as the HTTP API `cancel_order` payload.
+
+### Order Response Format
+
+**Success Response:**
+
+```
+{
+  "code": 0,
+  "message": "success",
+  "request_id": "bccc2b23-03dc-4c2b-912f-4315ebbbb7e0"
+}
+```
+
+**Rejection Response:**
+
+```
+{
+  "code": 400,
+  "message": "alo order rejected",
+  "request_id": "1187e114-1914-4111-8da1-2aaaa86bb1b9"
+}
