I need an indicator and an EA based on closing prices.

I need an indicator and an EA based on closing prices.

The indicator would be a histogram.

Parameter A: Number of close periods. Default: 10

Rules:

If Close > Close [PARAMETER A] -> Histogram green 

________________________________________________________

For the expert advisor:

Parameter A: Number of close periods

Parameter B: Take profit

Parameter C: Stop Loss

Parameter D: Start of Hours Trading HH: MM

Parameter E: End of Trading HH: MM

PARAMETER F: Make reversal? TRUE/FALSE. Default TRUE.

Same rule where Green = Buy and Red = Sell.

I would like to make optimized backtests with Parameter A and also with the exits criteria (B and C).

The take profit of the trade would be a fixed number of points: Parameter B

The stop loss is a fixed number: Parameter C

If the operation changes the signal make the reversal(Check PARAMETER F first).

Parameters D and E are to limit the EA to the day trade with more specific schedules that would be tested by me. If I leave it blank the EA would execute in Swing trade mode.
