Pi software's 'BackTesting' and 'Go Live' giving different results

Below is the strategy that i have used for backtesting

Buy Script: SOPK(9,3,9,SIMPLE)<20 AND RSI(Close,14)<45

Sell Script: 0

Exit Long Script: SOPK(9,3,9,SIMPLE)>80 AND RSI(Close,14)>65

Exit Short Script: 0

I used this strategy on 5min timeframe for 3000 candl’es, it gave me approximately 25 trades for 3months on a particular stock, however when i took this strategy today to ‘Go Live’ on that same stock; it gave me 40 alerts in the span of 1hour. It was giving me alerts for every minute even though i am using 5min candle’s (which i think is a bit weird).

Can someone please let me know what is it that i am doing wrong? I am eagerly waiting for someone to help me on this.

Do let me know if you need any more details, i will be more than happy to share.
