So, far this has been my safest strategy to trade Nifty:
Apply the indicator 'Risological Astra' Set Nifty to 15 min time frame BUY CE side if the price closed above the Astra dotted line. I buy the monthly contract ONLY, with this strategy. Sell 50% when the price reaches TP4. Hold remaining 50% till the price crosses under the Astra dotted line.
This trade gave me 315+ points (unrealized PnL) Ofcourse I will be selling 50% at TP4 and hold the remaining till the price crosses under the astra line.
