Nifty future which chart to follow

[TradingCodes.in]

@Bid

why Nifty or any other future stock not comes with more than 3 months data. i guess nifty future chart to follow rather than nifty50 spot chart price. but unable to plot many lines like 50 day EMA/SMA on that due do less time frame i guess.

While backtesting a strategy to implement on futures. Do we backtest it on spot instrument or the future contract itself. If the contract itself how do we backtest for more than the contracts period

@Bid

also no pivot line comes in day chart if someone can help please.

Pivots are intraday values based on Prev. Days OHLC
