And here are some so called profitable strategies...
Order Flow Trading
There's no such thing. You can see supply and demand (support / resistance). However, price is never overbought or oversold. Price is always right. There are anomalies but they are not easy to see. There's 50% probability that S/R will be broken or bounce. You can never know if someone going to click on the market buy/sell button.
Price Action
Even my random chart generator does have price action. It's all random and there are trends...
High Probability Chart Patterns
Nope! HS, engulf, pin bar... All of them tested. Your chance is still less than 50%
Trading Algos
They are not fake and profitable until they become losers. Most of profitable algos risk 4 or more to get 1. One day, they will lose all the money
Backtesting #1
I have coded a random trade simulator. This script enters a trade randomly. 1:1 RRR and traded more than 10.000 (simulated). However, system never but never won more than 49%. (no spread or commissions calculated). You can say, if there's 50% probability, how come system can not win %50? Of course it can not win. We have stop-loss at the same range. Sometimes, market stops us and goes back to target.
Backtesting #2
I have created a simple moving average strategy and put the script in a loop to find the best matched values. After a few hours, i had enough data and plots. However, i strongly believe that, winning algos will lose by time. Everything changes. They worked in the past and it doesn't necessarily means that it's going to work in the future.
