The best way to make money with trading is to use the darvas boxes with "different time frames".
If you want to keep your money, you need a strategy.
Don't forget, it's not important how much money you've made. The most important thing is how much you kept!
If your stated strategy keeps and maintained your trading funds and continously earns for a long period of time then good. Just continue on your doings. People have different strategies so keep those while learning new things things on the road.
Anyways agree on your last statement but of course make sure that money you will made is worth your time and effort.
