Genius Strategy or Just Controlled Martingale?

I came across a trader named Jean François Boucher on YouTube who claims to have a 94% win rate. His trading style is quite unique. He trades EUR/USD for just two hours during the NY session, plotting key levels and creating a 9-pip box, which he then copies to form a 9-9-9 pip grid boxes. He takes trades at key levels with a 3-pip TP and a 36-pip SL which seems like risky risk management. However, he uses multiple orders to manage risk. If the market moves against him, he adds another trade in the same direction and continues doing so until the market moves in his favor. It’s hard to explain in text, but you can watch his videos(below yt links) What do you guys think is this strategy actually profitable? 1 : [https://youtu.be/e8geZBKG28U?si=k4VLwvo4b8xdCOVF](https://youtu.be/e8geZBKG28U?si=k4VLwvo4b8xdCOVF) 2 : [https://youtu.be/xf2A3kUmpFY?si=i9w-BOWP\_SF8XFfe](https://youtu.be/xf2A3kUmpFY?si=i9w-BOWP_SF8XFfe) https://preview.redd.it/w779mp046hke1.png?width=598&format=png&auto=webp&s=4839896794bfafdcf7fb076b3206c28f4ec8758e
