Hello everyone, i am making this post at my lowest of lows(in life and in trading).
I have gone round and round in circles (from “retail” trading patterns/systems to “smart money” systems and back again to retail) but still no results.
I have spent hundreds of dollars buying courses (in which the creators are always cherrypicking when they backtest, use the replay tool or when picking an example,, sometimes i literally scream out! “What about this point here! Why did you skip it!”) but nothing seems to be working.
I do not intend to give up on trading because i have seen what it can do for people. Or is everyone else like me? Unprofitable and then starts selling courses or mentorship?
I need help! I need to be pointed on the right direction and guided. Life is tough and only getting tougher.

Deleting everything and starting over with signals would be incredibly stupid.

Here's my advice, because a trade is a trade and an auction is an auction (you're trading at an auction, hence the bid/ask). When you look at something like USD/JPY, replace JPY with an item you've bought and sold before. Now you'll know what to do because you've done it before.

If you go to the gas station today and it's $3/gal, your car sits at home not being used and next month gas is $4/gal. You could sell the gas in the tank for more money, right? Pretty simple. Now guess what you just did there.
