Yeah, you so right. This TA prophets everywhere start to be Annoying!
Irrationality of markets is so strong that I start just wagging most probable scenario out in my TA analyses. Many times my predictions are turned up side down and the only life-save jacket is how to manage risk.

If I had been successful in my trades I allow to reward myself with more risk. If I blow up, my risk margin have to be shrunken. (I think that this is called anti martingale risk management to be little technical).

If I am doing very badly sometimes I forbid trading to myself to cool down and power up my scenes.

It's fck*g simple :-)
