Modify EA

Hello! I have an EA and I need to modify as per below :

1. Take profit TP1 - once open trade is triggered, TP1 to be set as 1 ATR ( adjustable) and 50% of the trade to be closed once TP1 is triggered.

Remaining of the trade to be left open until TP2 is reached, or closing of the trade will be triggered by one of the indicators.

2. As you may see in the attached picture, my indicators sometimes will allow the trade to open very late in the trend and this I would like to avoid.

Somehow to create a condition ( adjustable) to avoid that. As example, if my 2 line indicator will flip for a buy condition, but volume indicator is NOT allowing the opening of the trade until 5 candles later, to avoid opening that trade. As you may se in the attached picture, if the trade is not opened in the green square area, the is no point opening later, just wait for another opportunity.
