When you watch those vids, you may get the impression that you have to code up a backtestable system.... and that's not correct. There are successful traders out there who have never used backtesting software. But there are a few things I've noticed successful traders have in common:
1. a very high level of concentration and patience 2. an eye for detail, even down to the tick. These guys notice everything. 3. a precise set up that they follow every time 4. an exit strategy for every trade - they don't enter without knowing exactly what they'll do if it moves against them. 5. they keep records and are very organized 6. they enjoy the process and are positive about what they're doing.
There's probably a lot more requirements. Unfortunately I lack a few of these, but it's possible to be strong in some areas and still do ok. You can see on those vids the degree of sophistication some of them undertake. These are the guys taking everyone else's money.
