hi T
With respect, I will defend attitude that there are no bad trading periods, only bad traders. During trending period best ones will earn most - results will make them best. During choppy (or trendless) periods those will lose least possible - result will also make them best. Like car race, on straight paths speed is most important, while on curvy roads avoiding falling out of street is most desired skill. We don't say 'bad times for racing' driving thru this part.
Finaly, using 'hard time for trading' sintagma is counterproductive because it implies war-alike environment comparing trading with fighting. Quite contrary, good trader is in line with the market, there is no hostile situation ever for him/her. If you want to look at trading business in war terms, then market and skilled trader are on the same side, fighting together against those that think market is enemy.
There is really pure and simple distinction between best traders and 'good' ones, during all times: those who earn more in the end are better. I understand your problems during recent 'choppy' times, but it's maybe because mechanical system still cannot beat skilled discretionary trader. It's up to you to find better way. Result, and not path to it is again only thing that counts.
Similar, I cannot find one excuse for recent bad period of many hedge funds. They are good, but they are not good enough, because they didn't change system fast enough. If you look at charts a few years back, you will see literally sea of (missed) opportunities. In this business there are no excuses, like there is in other businesses.
Re. trading as inherited skill, I strongly believe it can be learned without special talent (I'm good example)
regards and be friendly with the Market
