I went with parents to visit my family on █████████████.
It was a 4 hour long road. █████████████████████████████████████
The biggest reason for why I even came was because I wanted to meet my cousin. A few months ago he told me he found a trading strategy that worked on any chart, even randomly generated ones. Ofc I tried to tell him that it wouldn’t work, but he couldn’t be convinced otherwise. We argued for a bit online, but I just abandoned it after I deemed it impossible to convince him.
So we kinda immediately started to talk about all this. He offered to go on a walk, and I agreed.
We spent the whole walk arguing about the same thing. He had this weird strategy that I’m not gonna bother explaining (because it was hard for me to even understand in the first place), and he was convinced that it was "fundamental law of charts". The most interesting thing about all this, is that his mistake was in terms of understanding of randomness. I feel like it’s a bit uncommon thing to get this mistaken in.
He was very convinced that he could basically «fool» the randomness. There was many things he talked about, like Martingale and "just buy while your strategy is down temporarily". It was practically impossible to convince him otherwise. We came back home, and I was kinda dumbfounded. I offered to try to write a backtest for his strategy, but quickly realized that it had just too many small rules and nuances that would be hard to represent in code. Regardless, I’m here for only 1 day, so I would definitely not have time to do this.
I then realized I could just quickly code an exchange emulator that would use random walk for price. And so, after a hour of coding with him watching me do so, it was born.
This was funniest thing I’ve seen for a while. He did a few tries, telling me that chart was behaving weird and to tweak some things (like switch it to OHLC, I did so but it didn’t change the values at all lol), but his hopes and dreams got crushed really fast by this thing LMAO.
He finally recongized that he was wrong. This finally opened up me being able to tell him how to actually make a real and profitable strategy, and we had a really good conversation afterwards.
