Binary Option Strategy Tester with Martingale

In Binary options, strategy testing is a bit different. The script is just a try to test Binary options strategies.
Assumption:

• We are opening position at next candle after signal come
  
• We are taking the position at opening price
  
• Our call will be profitable if we get a green candle and put will be profitable if we get a red candle
  
• We can open only one trade at a time. So if we are in trade, subsequent signals will be ignored.
  

The script is not counting your profit or loss, it just counting the winning and losing trades.

Input Options:

• Choose long only or short only test. Default is both.
  
• You can continue your trade with Martingale Level, up to 5. Default is 1 (no Martingale)
  
• You can choose Martingale trade type
  SAME: if call subsequent trade will be call only and vice versa
  OPPOSITE: if call subsequent trade will be put
  FOLLOW CANDLE COLOR: Subsequent trade will follow previous candle color
  OPPOSITE CANDLE COLOR: Subsequent trade will opposite of previous candle color
  
• You can choose trading session to test. Default is false.
  

The strategy is taken from Vdub Binary Options SniperVX v1 (by @vdubus). I have deleted extra parts and kept only the necessary part.
