Need coder help build EA momentum and Trend trading

Dear FF coder,

i have a concept of building EA follow trend and momentum, i have done manual backtest with mt4 and i found it would be profitable, so please find my concept as below:

- Strategy base on RSI 14 + EMA 200
+ RSI period can customize, but default period 14 and EMA too
1- Buy condition : RSI above 70 level and Market above EMA200,
+Take profit: 20 (customize),
+Stoploss= customize,
+ but i prefer Martingale option: Pipstep= 500 point and Multiplier= 1.5 , when entry is loss.

2- Sell condition: RSI below 30 level and Market below EMA200
+Take profit: 20 (customize),
+Stoploss= customize,
+ but i prefer Martingale option: Pipstep= 500 point and Multiplier= 1.5

3- Lots size can bel Manual or Auto base on Balance risk %

My English is not good enough to explain you detail, so if you have any question for more detail please reply.

Thanks in advance,

Loka
