Supertrend system - (anybody can do it with Easylanguage,too??)

Supertrend system with martingale (instead of stop) and higher timeframe trend filter.

supertrend is a kind of trailingstop, which calculated from the average candel price and the atr: upper line for the shortcover: (H+L)/2+xATR  and lower channel line for the long stop: (H+L)/2-xATR
I have a SuperTrendCorrect.ex4 indicator for the signals..

• open an initial position in the supertrend direction.
  

• if the position goes towards in the profitable direction, then keep it, until the signal reverse. then reverse the position.

• if the pos goes against us, then double the initial lot size at every yATR level. (show this next yATR level with a line)

• make this martingale (doubleing) function turnable on/off

• when it turned off, then let the supertrend opposite signal the stop level. (simple reverse mode)
  
  
• show the margin call level with a red line,too, if it possible..

• a filter: let I choose a higher timeframe, in which the supertrend determine the main direction of the trades. (and within this main direction computed the lower timeframe supertrend signals, martingale/or not martingale mode)

inputs:

• lower timeframe: m5
  
• x (xATR multiplier): 3
  
• ATR period: 10
• yATR (doubleing level): 3
• shifting z pip: 0
  
• martingale on/off: on
• max doubleing (martingale) number: 5   ---here I wait any suggestion, how can I avoid the margin call??
  
• higher timeframe ST filter: on/off
  
• filter (higher) timeframe: 1h
• MM rule - the initial pos size is a % of the free margin: 10
