I need a couple of very commonly used features added to an existing Expert Advisor.

I have an EA that contains nice and clean code.

I would like to add a couple of commonly used features:

1. Support & resistance stop loss option i.e. x amount of pips above x amount of previous candles for sell and opposite for buy.

2. Set a maximum stop loss to override.

3. option of lot size based on current account balance i.e. x % of risk.

6 inputs to add

 choose stop loss type: fixed/support& resistance

Support & ressistance:  candlesback to look

Support & ressistance: amount above/below the particular candle

Maximum stop loss

lot size type

amount/percent risk
