Binary Option Ultimate Backtester-V.1[tanayroy]

The Binary Option strategy backtester gives the user extensive power to test any kind of strategy with advance trade management rules.
The strategy tester accepts external scripts as strategy sources. You can add your strategy and test it for historical stats.
Few assumption regarding strategy tester:

• 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.
  

How to make your strategy code compatible for strategy backtesting?
In your strategy code file add following lines:
Signal = is_call ? 1 : is_put ? -1 : 0
plot(Signal, title="🔌Connector🔌", display = display.none)
Is_call and is_put is your buy and sell signal. Plot the signal without displaying it in the chart. The new TradingView feature display = display.none, will not display the plot.

All Input options
Group: STRATEGY
Add Your Binary Strategy: External strategy to back test.
Trade Call/Put: Select CALL, to trade Call, PUT, to trade Put. Default is BOTH, Trading Call and Put both.
Number of Candles to Hold: How many candles to hold per trade. Default 1. If you want to hold the option for 30 minutes and you are testing your strategy in 15m intervals, use 2 candle holding periods.

GROUP: MARTINGALE
Martingale Level: Select up to 15 Martingale. Select 1 for no Martingale.
Use Martingale At Strategy Level: Instead of using Martingale per trade basis, using Martingale per signal basis. Like if we make a loss in the first signal, instead of starting martingale immediately we’ll wait for the next signal to put the martingale amount. For example if you start with $1 and you lose, at the next signal you will invest $2 to recover your losses.
Strategy Martingale Level: Select up to 15 Martingale at strategy signal level. Only workable if Use Martingale At Strategy Level is selected.
Type of Trade: Martingale trade type. Only workable if we are using Martingale Level more than 1.
It can be:
“SAME”:If you are trading CALL and incur a loss, you are taking CALL in subsequent Martingale levels.
“OPSITE”: if you are trading CALL and incur a loss, you are taking PUT in subsequent Martingale levels.
“FOLLOW CANDLE COLOR”: You are following candle color in Martingale levels, i.e if the loss candle is RED, you are taking PUT in subsequent candles.
“OPPOSITE CANDLE COLOR”: You are taking opposite candle color trade, i.e if the loss candle is RED, you are taking CALL in subsequent candle.
