If you are new to trading Swing or daytrading, I cannot stress enough that you MUST paper trade for at least 1 month.
You MUST be honest to yourself when paper trading, that means keeping accurate record of all your losses and gains, without making excuses.
Only when you have succesfully paper traded for over a month, do you proceed to the real thing.
Last and most important advice I can bestow on you is.
By all means, you MUST set stop lost and hang on to it.
It does not matter how often you win, the game is about surviving.
High flyers who dont set stop loss well eventually succumb to the market.
