Would be good to know what are traders worst months to get an idea to trade less or downsize. Any studies or stats been done on it?
Not sure if there is anything like that. It boils down to the type of traders and the strategy they use. Maybe some months or season is good for certain types of trades. The election seasons in the US do makes some pairs act in certain direction. However, nothing is certain
my worst month began when loses during news , i passed a minimum time in this trading placed but still doing loss in news trading.
At these moments, for over a year each month, only profit. One month is better, the other is worse, but it's a plus.
I used to have a bad month in December, when at the end of the month you can see a "thin" market, where unexpected and unanalyzable sharp price movements are possible. So now I do not trade at this time.
