To be patient and vigilant when you have to be and to be greedy and enthusiastic when you have to be - often at moments that you least expect or naturally feel like.
Example - You've been waiting for a settup for most of the day and yesterday you didn't trade at all.
Then you spend half an hour slowly working up an appetite to put on a trade, when everything lines up just right. And then, just when your about to put on the trade, the very last one minute bar gives you a "no go" type signal not in a big way, but it is there. You must be disciplined to follow it, not easy in some personal circumstances, especially if you missed that big move on Friday.
Then you might have to wait another ten minutes to feel vindicated for not getting in. In those ten minutes there are many reasons to get in - and one false move and the trade is a looser. After that, same process again. 15 minutes later a very similar signal pops up (before it took 30 minutes to form) and then again, that very next one minute(or tick) bar gives that same "no go". Next bar, same again as before.The next bar though is a breakout bar - not a big one - but enough to signal that everything is a go. Put on a trade at this point - it is very difficult to do.
