There's one thing I can't explain

Now I'll hook it to n. 6 forex pairs, with two charts for each pair. In practice, on one graph I set it ONLY LONG, while on another graph I set it ONLY SHORT. So work both ways. When there are many open positions at a certain point he stops opening other contrary positions on other pairs and continues with only one. When he manages to close he makes a nice profit and at the same time cleans everything he has opened, absolutely everything.

When the software starts to open positions by martingale, at the beginning it also slightly increases the pips of TP (example 10 pips) as it increases the positions (counter-trend) it gradually increases the pips of TP reaching approximately 18-20. These are stable, then at some point they begin to decline again.

Conclusion for EA:

When current candle close above last candle high, execute BUY.

When current candle close below last candle low, execute SELL.

Martingale until closes in Profit.

Multiplier is adjustable.

Distance between layers is adjustable.

Group of Layer TP is adjustable.
