I am an intraday and positional trader with 10+ years of coding experience. I have starterd a paid service to get your trading strategy backtested on Nifty, BankNifty, Nifty100 stocks, Nifty options & BankNifty options. I will write code exclusively for your strategy, and backtest it on past many years of data. Few months of analysis will be provided for free for the choice of your underlying. If you like it, you can request for more months by paying a small fee.
For each backtest, there will be a fee of Rs. 75 per scrip for each additional month of analysis requested.
