I have been practicing meditation on my trades. For no other reason than to learn to still the mind seems to me have no possible downside with the benefit that it takes me away from scrutinising the trade as it hovers around between stop loss and take profit and therefor reduces my stress levels.
I have only done 5 or 10 mins here and there though as I just started last week. I find it very hard to stop thinking about anything. It is something that needs to be developed for sure, like a muscle.
