I need 3 separate, one indicator based adjustable EA's.

Hello, I need 3 EA mostly for backtesting.
I will need the code to change settings in EA.
Main requirement is that I need to be able to adjust:
a)Take profit/stop loss
b)Lot size
c)Time frames
d)Basic indicator levels(pls refer bellow)

1)1st EA

2 Moving averages cross over strategy EA.
2 moving averages - open trade on cross over(depends if smaller period MA crosses bigger period MA from top(sell) or bottom(buy)). I need to be able to adjust periods of moving averages + things I mentioned in begining.

2)2nd EA

RSI based EA
Open trade if RSI reaches certain level (for instance: If reaches 80 - sell, if 20- buy)
I need to be able to adjust RSI levels + things I mentioned in begining.

3)3rd EA
MACD based EA 
I need EA open trades when MACD reaches 0, with condition that it should have reached certain level bellow(and that level should be adjustable) + things I mentioned in begining.
