It hurt with fake money, because I thought I had discovered some big secret key. Like that movie Pi. And then it was gone. All the sucess, all the dreams of a 9-screen batcave-style computer station with financial tickers and shit. I realized that I had nothing, and I was foolish for thinking otherwise. Stung like a bitch.
But you're right, safe investments are the smarter long-term play. I did make an extra paycheck on dogecoin once on a moonshot. But otherwise, my boring retirement funds are all steadily beating inflation by a few percentage points. Why fight the tide?
It is, but forex markets allow traders to trade on significant margin. Meaning, if I have $100, I might be able to buy $1,000 worth of foreign currency (a 1:10 margin) and if the value of the currency increases 1% ($100) you get 10% of the profit, which is 10% of your investment. If the position increases by 10%, you double your money. However, this also means that if the value drops by 10%, your money is gone.
Now consider that forex traders often leverage at 1:500 margins. You get to buy massive positions with currency pairs, and even the tiniest fluctuations can provide massive profits or instantaneous ruin.
The algorithm I used monitored recurring micro-patterns, watching for predictable movements. You're also watching relative value pairs, rather than just an absolute market value. Both sides of a currency pair have nations vying to improve the value of their own currency, so you can make money (or lose money) on either side of the pair. Dollar is low against the yen, buy dollars with yen. Yen drops against the dollar, sell your positions. Euro drops against the yen, go pick up Euros agains the yen, and feel confident that Japan is already trying to strengthen the yen (simplified example, because it's way more complex than that).
So if you track currencies across all currency pairs, you can find inconsistencies. I called it "torque" 15 years ago, but I'm sure a proper forex trader can give you an actual name for it. These are areas where three or more currencies are out of alignment, like if the dollar is up against the yen but down against the euro, and the yen is up against the euro. These are situations where you would expect the market to equalize in one direction or the other, and the trick was being able to predict which way it would go.
And I thought I had figured that out. I had not figured that out. I had gotten lucky several times in a row.
