Hey Product Hunt! I built TradeFlashApp because I wanted a better way to practice reading charts without risking real money. The problem I kept running into was pretty simple: with live markets you have to wait to find out if your idea was right, and with historical charts it's really hard not to look at what happened next. So I started building a small tool for myself around a different idea. TradeFlashApp puts you at a random point in real historical market data and hides everything after it. You look at the chart, draw where you think the price is going, lock in your prediction, and only then reveal what actually happened. The app compares your prediction with the real movement and gives you a score. Then you can just jump into another scenario and do it again. What I didn't really expect when I started building it was how addictive this loop would be. I showed an early version to a few friends and they kept wanting to try "just one more chart" to beat their previous result. That's when I thought this could be more than just a little tool I made for myself. There are still a lot of things I want to improve, especially the scoring system and different training modes, so I'd genuinely appreciate feedback from people here. There's a free version if you want to play with it. And if you try a few scenarios, I'm especially curious about one thing: does it make you want to do one more?
