Range-breaking Strategy This example highlights how to create a strategy by adopting custom rules **Open position** Long Position: Break above the last 60-minute peak Short Position: Break below the last 60-minute trough **Close position** Close long Position: Break below the 10-minute peak Close short Position: Break above the 10-minute trough ## 1.1 Rules on new creating #### 1. Long position opening **Conditions** price("BTC_USDT", 0, "usdt") > max_price("BTC_USDT", 60, "usdt") and order_collateral("usdt") ==0 and position("BTC_USDT", "usdt") == 0 （1）price("BTC_USDT", 0, "usdt") > max_price("BTC_USDT", 60, "usdt") This condition means that the current BTC perpetual contract price is greater than the highest price in the last 60 minutes. （2）and order_collateral("usdt") ==0 This condition means that there are no pending orders for the current strategy; order_collateral is a predefined function, which obtains the margin of the unfilled orders. If the return value of this function is 0, it means that there are no pending orders for the current strategy. （3）and position("BTC_USDT", "usdt") == 0 This condition means that the current position size of the strategy is 0, and position is a predefined function. It indicates the position in specified market for the current strategy. **Execution logic** Type: Contract Trading; Market: BTC/USDT Perpetual Contract; Order Type: Limit; Leverage: 5X; Side: Long; Limit price: bid_price("BTC_USDT", 1, "usdt"); Size: 1. ![](https://gimg2.gateimg.com/image/article/1666695407image.png) #### 2.

For example, the "range" custom variable should be executed first, followed by the opening and closing conditions in the order 2 to 5. ![](https://gimg2.gateimg.com/image/article/166669807010.png) Gate reserves the final right to interpret the product.
