Learn futures ES, NQ, YM, CL, E6 etc Why invest your time in this, how it can help you to become profitable? Every successful trader and many here on this blog in your threads have already stated - the key is to found what will work for you. To walk from system to system is only losing your time. Every profitable system is good, the answer is the trader who is performing it. And I learned that you are already profitable for ten years- so what more, continue to use your system and for intraday just in a shorter timeframe, as somebody already suggested to you here. Good luck!
Your biggest edge as a trader is to be able to take a stop to protect capital and let winners run, when you daytrade your winner, is limited by time, you can let it run, but only for so long; and this is a very limiting factor. Long story short, daytrading is a pipedream (for the most part), I suggest swing trading or position trading.
Medium-long term is easier but intraday allows you to devote full time to what you like. It's my dream.
Yes! here is my holy grail for intraday: Take a dice and throw it, if a even number comes up you go long ES, if odd number stay out and try again in 30 minutes. Set a fixed profit exit at 0.30% and fixed stop loss at 0.10% Try it, it will work!
