Automating My Price Action Strategy

The Strategy is:

1) Entry Rules: a) Price is above 200EMA b) Price Action Signal forms at 50MA (Acceptable price action signals include pin bar, hammer head/inverted hammer, engulfing candle, 2-candles reversal and doji. Signal candle must pierce the 50ema, but must close above it or below it for sell signal) c) Buy or sell when price breaks the high (or low) of the signal candle. The period of the signal moving average should be a variable that I can change to 100, 80, 20, 10 or even 5.

2) Exit with loss: Stop Loss should be 3 pips below the low (or high) of signal candle.  Number of stop loss pips below (or above) the signal candle should be a variable that I can change to any number. 

3) Exit with profit: I have not made up my mind on exit with profit rules. When I trade it manually, I use support and resistance to determine my exit. In terms of automation, I may need suggestions on viable exit with profit rules.

4) Filters: a) Signal EMA must be pointing in the direction of the trade (up for buy and down for sell) b) Please you may suggest other filters for my consideration

5) Other conditions: EA should work for all currencies and aĺl time frames.
