Being profitable! LOL Strategies change as the market changes, at least for me. Being adaptable is important. Forcing strategies that have quit working is a sure way to fail IMO.
Not a strategy but continued self improvement, money management, emotional control, knowing the time of day, whether we are up down or sideways. The market is like an amoeba, constantly changing, you have to adapt with it.
the thing that has always worked is to buy quality stocks that have low debt a history and make money when they are down and hold them until you get a nice return. its not very exciting and sometimes it takes patience but it works. some of the more notable ones that i sold too soon this year. hd s bby c pfe cum wmt csco pvn cof. its not as exciting as the guys who claim to make 25% or more a week scalping the es but does the job.
Sorry not got ten years... Finds stocks breaking Daily trendlines, long or short... BUY or SELL when price retraces to 20 move average... The rest is judgement....
having a workable routine being cautious overall but loading the gun a few times a year when warranted
