固定止盈和止损的问题

Question

I'm very new to coding and am hoping someone can assist me with the strategy code below. The goal of the strategy is to detect when the ADX/DI is above the user selected filter and the EMA is above the user selected filter for longs and below the user selected filter for shorts.

For example, User selects ADX/DI filter to be 35 and EMA filter to be 29.

For a Long Trade If ADX and DI+ is over 35 and price closes above EMA 29 then long trade will be opened. Long trade will close when the user defined fixed take profit or stop loss is hit or when a Short Trade is triggered

For a short trade If the ADX and DI- is above 35 and price closes below EMA 29 then the short trade will be opened. Short Trade will close when the user defined fixed take profit or stop loss is hit or when a Long Trade is triggered

The issue is I am not able to get the Take Profit and Stop Loss to work in the code. Would someone be able to assist?

If you want 3.5% TP and 2.25% SL:
