Caught a nifty swing in the cash market today, intraday magic or just lucky timing?

Tried something from a paper I stumbled upon last week. Wasn't sure if this logic would work, but the idea was to use a simple moving average crossover for intraday in the cash market. It seemed almost too straightforward, yet the backtesting showed promising results. I set up a basic algo to execute trades automatically, and surprisingly, it caught some nice swings in Infosys and TCS today. The adrenaline rush was real, but I'm wondering if this is just beginner's luck. Is anyone else exploring algo strategies for intraday in the cash market? Open to feedback and insights from fellow traders!
