Price action EA

hi, 

i need a trading robot with the following specifics:

- input parameter: timeframe, volume fixed lot, stop loss (in pips), trailing profit (in pips), take profit (in pips)

- algo is based on price action:

BUY: if bar closing price is higher than the medium price of the range bar price (or 3/4 of the range bar price....maybe an input parameter?)

SELL: if bar closing price is lower than the medium price of the range bar price

I need to add the range bar price as an input parameter, so i can optimize that with backtesting for every simbol.

Please see the attachment file to better understand: 

Bar 1: the closing bar price is not lower than the medium range bar price --> false sell signal

Bar 2: the closing bar price is lower that the medium range bar price --> sell signal
