100% Winning strategy. Is it even possible?

I have been into strategy building and algo trading and I’ve built something which seems to show 100% win days in the past 2 years of back testing data. I know as a matter of fact tur it can’t be that high but even at worst case scenario, it is easily 90%-95% accurate. I want to discuss if this is a possibility. Also to mention, apart from backtesting, I have done about 2-3 weeks of forward testing with about 100 trades made out of which only 1 was loss maker. I deployed it using real capital and made 2 trades. Both gave profit. Have I found some loophole or something?
