I want an expert advisor based on a trend indicator.

The opening of the order will be based on the trend of the indicator, when the color signals BUY, the order will be executed at the maximum of the signal candle. And when the color signals SELL, the order will be executed at the minimum of the signal candle.

The expert advisor must contain:

lot:
exponential lot:
pip step:

TP:
SL:

Magic number:
Max spread:

Note: Improvements and ideas are welcome. Anything to improve the performance of the expert advisor.

I need urgency.
