I want to scan nifty 50 scripts including nifty futures & Banknifty fut. Alert signal has to be given if any of the below happens:

Buy when ema 15 crosses over ema 20 in 5 mins candle (SL ema 20 on candle closing basis)

Sell when ema 20 crosses over ema 15 in 5 mins candle (SL ema 15 on candle closing basis)
