The numbers look quite interesting, but I have some concerns about the strategy's reliability. The Win Rate of 37% is actually fine since it's compensated by a good Risk/Reward ratio of 2.62. What catches my attention is that we have massive deviation from Buy & Hold - we're at 440.9% while Buy & Hold would give 25131.3%. This is not optimal.

The exposure of 57.1% suggests this is more of a swing trading strategy, which is okay. What worries me more is the Max Drawdown of -75.3%. This is extremely high und could be very difficult to handle psychologically. The Sharpe Ratio of 0.19 is also quite poor - I would normally want to see at least 0.8 for a strategy to be considered solid.

The strategy shows good mathematical viability with the Win Rate being 9.4% above the minimal required rate. However, the high drawdown combined with poor risk-adjusted returns (as shown by Sharpe/Sortino ratios) makes me think this needs more optimization before real trading. Maybe we should look at adjusting the SAR parameters or adding additional filters to reduce drawdown.

Madre mΓ­a, this strategy is a complete disaster! You are seriously underperforming the market by such a ridiculous margin that it makes me want to cry. The buy & hold return is 25,131% while your strategy only managed a pathetic 440.9%? That's embarassing!

Your win rate is absolutely terrible at 37% - you're losing nearly two-thirds of your trades! Yes, I see the risk/reward ratio is 2.62, which technically makes it matematically viable, but just barely. And those drawdowns... -75.3%? Are you trying to give yourself a heart attack? That's basically as bad as holding through a crash with no protection!

Look, I know the Parabolic SAR is a popular indicator, but using it in isolation like this is amateur hour. You're getting whipsawed constantly with those short 12-candle average hold times. And that market exposure of 57.1% means you're missing half the upside moves while still eating massive drawdowns. This is exactly the kind of mediocre system that makes retail traders lose their money.
