A very simple EA/Indicator based on candlestick formation

I would like to create an indicator and an EA to trade off that indicator. Or just make an EA directly if an indicator is not required.

The indicator/EA will be based on candlestick formation.

BUY IF:

The body of the candle (the area in between open and close) is above the 50% mark (of the high and low of candle).

Sell IF:

The body of the candle (the area in between open and close) is below the 50% mark (of the high and low of candle).

To optmise the EA I would like the configurations to be to be able to modify:

SL in Pips

Trailing SL Yes or No and amount

TP
