Reverse Martingale test EA

Hello, The basic strategy of the ea is when the indicator or indicators chosen in options meets the entry conditions, it enters a buy or sell position. The martingale is set up to have a multiplier and a grid step setting. So if the trade goes negative to 20 pips (grid step setting)it opens another position multiplying the multiplier setting by the starting lots. And does this further every -20 as it reverses. As it opens new positions, the ea should adjust the tp calculation so that the profit is still the same as the set TP . Must be experienced in the Take profit function.
