+# Filters
+
+Filters define trading rules on a symbol or an exchange.
+
+## Symbol filters[](https://developers.binance.com/docs/derivatives/options-trading/common-definition)
+
+### PRICE\_FILTER[](https://developers.binance.com/docs/derivatives/options-trading/common-definition)
+
+> **/exchangeInfo format:**
+
+```
+{  "filterType": "PRICE_FILTER",  "minPrice": "793.112",  "maxPrice": "1189.668",  "tickSize": "5.000"}
+```
+
+The `PRICE_FILTER` defines the `price` rules for a symbol. There are 3 parts:
+
+-   `minPrice` defines the minimum `price` allowed; disabled on `minPrice` == 0.
+-   `maxPrice` defines the maximum `price` allowed; disabled on `maxPrice` == 0.
+-   `tickSize` defines the intervals that a `price` can be increased/decreased by; disabled on `tickSize` == 0.
+
+Any of the above variables can be set to 0, which disables that rule in the `price filter`. In order to pass the `price filter`, the following must be true for `price`/`stopPrice` of the enabled rules:
+
+-   sell order `price` >= `minPrice`
+-   buy order `price` <= `maxPrice`
+-   (`price`\-`minPrice`) % `tickSize` == 0
+
+### LOT\_SIZE[](https://developers.binance.com/docs/derivatives/options-trading/common-definition)
+
+> **/exchangeInfo format:**
+
+```
+{  "filterType": "LOT_SIZE",  "minQty": "0.0001",  "maxQty": "1000",  "stepSize": "0.0100"}
+```
+
+The `LOT_SIZE` filter defines the `quantity` (aka "lots" in auction terms) rules for a symbol. There are 3 parts:
+
+-   `minQty` defines the minimum `quantity` allowed.
+-   `maxQty` defines the maximum `quantity` allowed.
+-   `stepSize` defines the intervals that a `quantity` can be increased/decreased by.
+
+In order to pass the `lot size`, the following must be true for `quantity`:
+
+-   `quantity` >= `minQty`
+-   `quantity` <= `maxQty`
+-   (`quantity`\-`minQty`) % `stepSize` == 0
