The main value i have found from Trading forums is helping to keep up with industry changes. eg Changes to regulations you might have missed, new products that become available, new brokers, new software... There is also the jokes aspect, entertainment. Making market calls is certainly a part of that. From an education perspective there is not much to be learnt. Forums are full of desperate traders looking for the holy grail of trading (100% a month, just like the OP is claiming). In reality profitable trading boils down to winning on few big trades a year with a win rate that normally ends up below 50%. Exactly the opposite of what the OP is doing.
The data is not 100% accurate, indeed it should be the YM market will closed up more than 65 points in uptrend and less than 70 point in downtrend for 65% of the time. This is just a 101 quant training (I went through this in day 1 when i started my job 15 years ago). Our machine learning have done this billions of times with different iterations and no edge has been found until today The only way to prove you are real (and better than the machine learning) is to trade on Real time with Live Calls.
Then what? After 30 or 40 trades. Will it be followed by explanations of the trades? Will these explanations be shared freely or will they have to be purchased?
yes, real time, with real money, is the ONLY REAL test. But carry on......sometimes things can morph into that...
You are really desperate to learn, just beware of the snake oil salesman or vendors. The best way to learn is to get a higher educations, and try to get a job placement in one of the institution. You will learn the real skills there.
