What I do is to avoid trading too often ..space out my trades to avoid impact of emotions on my results
As you can see below, on average I trade 5 to 7 times per month...
This helps to minimize the effect of emotions of winning trades (euphoria, arrogance) or losiing trades (anger, revenge seeking) on your objectivity.
So for example, so far for February, just 2 trades have been made with the last one a 100 Pip gain on the GBP JPY on Monday during the market sell off..
Now this kind of gain in just 5 hrs could easily tempt me to greedily go after more pips even when it is not viable to do so. But because my type of trades arise just 1 to 2 times a week, I can easily come down from that high to calmy wait for the next trade.
Emotions canbot be avoided but by spacing out your trades, you can ninimize its effects on your trading results.
