Why is nobody making a fully loaded Backtesting tool like Fxreplay or Traderscasa etc . in India . Manual backtesting with features that Fxreplay or similar platform allows is such a game changer. You can literally backtest so easily and find your edge.
Why no Indian company is doing that ?
You can do replay trading in Tradingview but even that lags and isnt optimal enough, as it doesnt offer so many features.
You can use Streak to Backtest your trading strategies.
streak is not good accurate why because form chartink and streak i was write both scripts are same but the live screener is slight delay and slightly stock missmaching in streak compared to chartink
Pinescript feature in Tradingview allows backtesting with as complicated rules as you can think of on any instrument. I personally have backtested many strategies on it. Try it out.
Even Zerodha made a youtube video on how to leverage AI to create pinescripts for backtesting. You should check that out.
