MQL5 EA request - Simple entry/exit rules with trailing stops

Hi,

I would like to create a very simple EA in MQL5 with the following entry/exit rules:

1. Entry Rules: EA will open a new trade at any given time setting up a SL and a TP. In case the price go against the price will set another trade in the opposite direction with another SL and TP but with a different position size.

2. Exit Rules: TP reached or in case there are two open trades when the aggregate profit is positive.

3. Trailing stops will be required.

The rest of the parameters and filters will be provided separately once the offer has been agreed.

Thanks for your time.
