-------------------------------------CONCLUSIONS (with some assumptions as best estimation of the odds)------------------------------------------------
Speaking of the odds of being consistent profitable as experienced trader, where you should have a decade of market experience.
7.7% of all experienced traders can trade consistently.
Only 3% of day traders make consistent profits. => So swing traders being consistent profitable is easier.
5% of all Forex traders are consistent profitable (=(100%-99.6%)/7%). => So being consistent profitable as experienced traders on Forex is more difficult than other asset classes.
After you traded for one decade daytrading Forex is most difficult, but swing trading non FX products is easiest to get consistent profitable. Your odds to be consistent profitable after that decade of experience are somwhere between 1:33 to 1:13.
So the conclusions (with assumptions as best estimation here):
FX daytrading most difficult | Your odds are ~ 1:50 (with 10 years trading experience (!))
Non-FX daytrading second rank | Your odds are ~ 1:25
FX swing trading third rank | Your odds are ~ 1:12.5
Non-FX swing trading highest rank or least difficult (to be consistent profitable after 10 years of trading experience) | Your odds are ~ 1:8
If you have only little trading experience your chance of being consistent profitable are somewhere between 1:80 to 1:500 so between 0.2% to 1.25% depending on what asset class (FX or non-FX) and trading style (daytrading or swing trading) you trade.
(Of course all estimated odds, presented here, should be understood as average numbers as there can be of course some deviations of it for the individual trader.)
