Here's the best advice you can get.
Don't bet money you can't afford to lose.
At a bare minimum 76% of retail punters lose. Over time, it's closer to 95 - 99% and the number that outperform a simple buy and hold strategy is probably less than 99.9%.
And the post above shows the 'benefit of hindsight' which is totally useless when you're actually trading.
Best of luck.
