-## 常用命令
+## 交易所配置指南
+### Aster
+1. 将 `EXCHANGE` 保持为 `aster`（默认值）。
+2. 填写 `ASTER_API_KEY` 与 `ASTER_API_SECRET`。
+3. 根据交易对调整 `TRADE_SYMBOL`、`PRICE_TICK`、`QTY_STEP` 等精度参数。
+4. 一键脚本会自动写入这些变量，手动部署时需自行维护。
+
+### GRVT
+1. 在 `.env` 中设置 `EXCHANGE=grvt`。
+2. 填写 `GRVT_API_KEY`、`GRVT_API_SECRET`、`GRVT_SUB_ACCOUNT_ID`。
+3. 若使用测试网，可将 `GRVT_ENV=testnet` 并调整 `GRVT_INSTRUMENT`/`GRVT_SYMBOL`。
+4. 可选：提供 `GRVT_COOKIE` 或自定义 `GRVT_SIGNER_PATH` 以复用已有登录态。
+
+### Lighter
+1. 设置 `EXCHANGE=lighter`。
+2. 填写 `LIGHTER_ACCOUNT_INDEX` 与 `LIGHTER_API_PRIVATE_KEY`（40 字节十六进制私钥），其中`LIGHTER_ACCOUNT_INDEX`是你的账户索引，需要你在官网按F12观察接口请求获取，`LIGHTER_API_PRIVATE_KEY`是你的API私钥。
+3. 如需切换环境，将 `LIGHTER_ENV` 改为 `mainnet`/`staging`/`dev`；必要时指定 `LIGHTER_BASE_URL`。
+4. 交易对默认为 `LIGHTER_SYMBOL=BTCUSDT`，也可按需重写价格与数量小数位。
+
+### Backpack
+1. 设置 `EXCHANGE=backpack`。
+2. 填写 `BACKPACK_API_KEY`、`BACKPACK_API_SECRET`、`BACKPACK_PASSWORD`；如有分账户，补充 `BACKPACK_SUBACCOUNT`，默认填写主账户ID。
+3. 使用测试环境时将 `BACKPACK_SANDBOX=true`，并确认 `BACKPACK_SYMBOL` 与实际符号一致（默认 `BTC_USD_PERP`）。
+4. 可通过 `BACKPACK_DEBUG=true` 观察适配器详细日志。
+
+### Paradex
+1. 设置 `EXCHANGE=paradex`。
+2. 提供 `PARADEX_PRIVATE_KEY`（EVM 私钥）与 `PARADEX_WALLET_ADDRESS` 注意这是你EVM钱包的地址和私钥，建议创建全新钱包，不要放置无关资产。
+3. 默认连接主网，若需测试网，将 `PARADEX_SANDBOX=true` 并根据需要调整 `PARADEX_SYMBOL`。
+4. 复杂环境可额外设置 `PARADEX_USE_PRO`、`PARADEX_RECONNECT_DELAY_MS` 或调试开关。

 ## 常见问题
-
-- 你需要至少 50-100 USDT 的资金才能运行策略
-- 请在交易所自行设置 50 倍左右的杠杆，本策略不包含杠杆设置
-- 请确保你电脑/服务器的时间是准确的真实世界时间
-- 持仓方式需要保持单向持仓
+- 至少准备 50–100 USDT 资金以覆盖策略运行需求。
+- 杠杆需在交易所提前设置（建议 ~50 倍），程序不会自动调整。
+- 请确保服务器/电脑时间同步真实世界时间，避免签名过期。
+- 账户需保持单向持仓模式。
 - `.env` 未读取：确认文件位于项目根目录且变量名无误。
 - API 拒绝访问：检查交易所后台权限，确保开启合约读写。
 - 精度错误：同步交易对的最小价格与数量步长。

-## Common Commands
+## Exchange Setup Guides
+### Aster
+1. Keep `EXCHANGE=aster` (default value).
+2. Supply `ASTER_API_KEY` and `ASTER_API_SECRET`.
+3. Adjust `TRADE_SYMBOL`, `PRICE_TICK`, and `QTY_STEP` to match the requested market.
+4. The bootstrap script auto-populates these variables; manual installs must maintain them.
+
+### GRVT
+1. Set `EXCHANGE=grvt` inside `.env`.
+2. Fill `GRVT_API_KEY`, `GRVT_API_SECRET`, and `GRVT_SUB_ACCOUNT_ID`.
+3. Use `GRVT_ENV=testnet` when targeting the test environment, and align `GRVT_INSTRUMENT` / `GRVT_SYMBOL`.
+4. Optional: provide `GRVT_COOKIE` or a custom `GRVT_SIGNER_PATH` when reusing an existing session.
+
+### Lighter
+1. Set `EXCHANGE=lighter`.
+2. Provide `LIGHTER_ACCOUNT_INDEX` and `LIGHTER_API_PRIVATE_KEY` (40-byte hex private key).
+3. Switch `LIGHTER_ENV` to `mainnet`, `staging`, or `dev` when necessary; override `LIGHTER_BASE_URL` if endpoints differ.
+4. `LIGHTER_SYMBOL` defaults to `BTCUSDT`; override price/size decimals when markets differ.
+
+### Backpack
+1. Set `EXCHANGE=backpack`.
+2. Populate `BACKPACK_API_KEY`, `BACKPACK_API_SECRET`, and `BACKPACK_PASSWORD`; add `BACKPACK_SUBACCOUNT` if you trade from a subaccount.
+3. Toggle `BACKPACK_SANDBOX=true` for the sandbox environment and verify `BACKPACK_SYMBOL` matches the contract (defaults to `BTC_USD_PERP`).
+4. Enable `BACKPACK_DEBUG=true` for verbose adapter logging.
+
+### Paradex
+1. Set `EXCHANGE=paradex`.
+2. Provide `PARADEX_PRIVATE_KEY` (EVM private key) and `PARADEX_WALLET_ADDRESS`.
+3. The adapter connects to mainnet by default; enable `PARADEX_SANDBOX=true` and adjust `PARADEX_SYMBOL` for testnet usage.
+4. Advanced tuning: use `PARADEX_USE_PRO`, `PARADEX_RECONNECT_DELAY_MS`, or debug flags as needed.

 ## Troubleshooting
-- You need at least 50–100 USDT of capital before deploying a live strategy.
-- Set leverage on the exchange beforehand (around 50x is recommended); the bot does not change it for you.
-- Keep server/desktop time in sync with real-world time to avoid signature errors.
-- Make sure the exchange account is in one-way position mode.
-- **Env not loading**: ensure `.env` resides in the repository root and variable names are spelled correctly.
-- **Order rejected for precision**: align `PRICE_TICK`, `QTY_STEP`, and `TRADE_SYMBOL` with the exchange filters.
-- **Permission or auth errors**: double-check exchange API scopes.
-More step-by-step guidance is available in [simple-readme.md](simple-readme.md).
+- 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.
+- Accounts must run in one-way position mode.
+- **Env not loading**: make sure `.env` lives in the repo root and variable names are spelled correctly.
+- **Permission rejected**: confirm the API key has perpetual trading scopes enabled.
+- **Precision errors**: align `PRICE_TICK`, `QTY_STEP`, and `TRADE_SYMBOL` with the exchange filters.
