EA Based on big Candle near 21SMMAs

Hello folks,

what i want: basicly this strategy: https://www.youtube.com/watch?v=wbfXaqjIrJ0

please watch it completly

there are 3 SMMAs( 200, 50, 21)

if the close prices of an UserINput Candle amount above those 3, we are in an Bullish market. If the price closes for an UserInput Candle amount below them we are in an bearish market. 

AND for both of them: 

21 SMAA is not flat but showing in the same direction as trend we are in. The slope can be set in UserInput.

---> if these conditions are met, we are in an uptrend/downtrend

Entering a trade: We enter a trade if the following is met:

1. Uptrend/Downtrend -> see above

2 Price closes near the 21 SMAA (The range to be considered as "near" will be in points and the user can set them as UserINput)

3. We see a Big fat Candle in the Trends dircetion (Uptrend: Green candle, Downtrend: Bearish candle) 

Big fat means: The last candle Engulfs the candle before with XTimes The Amount can be set as UserINput (for Example 2X the size of the candle before) but the big fat candle must be minimum 0.8X the ATR (the X time here is also an UserInput)

--> If these condiitons are met: we enter the trade with a UserInput LotSize

Exit: 

TP: X Times the ATR from the current Ask/Bid (UserInput can set the Factor)

SL: X Times the ATR from the current ASK/Bid (UserINput can set the Factor)
