what you need about trading

i think it is that :

* Price either goes up or down.
* No one knows what will happen next.
* Keep losses small and let winners run.
* POSITION SIZE = RISK / STOP LOSS
* The reason you entered has no bearing on the outcome of your trade.
* You can control the size of your loss (skill) but you can't control the size of your win (luck).
* You need to know when to pick up your chips and cash them in.

Expectancy = (Probability of Win * Average Win) - (Probability of Loss * Average Loss)
You can not control the probabilities of wining or losing.


You can not control your average win size.
