One thing i personally struggle with is coming up with an idea worth the time investment of building it into a strategy (one thing I’m hoping this forum can help with!) A blog I follow had an insightful post about this very topic I thought I’d share for other indecisive traders http://www.cuemacro.com/2018/10/14/how-to-find-systematic-trading-ideas/
I find I come up with my best ideas when using a semi-automated approach to trading. Get a couple of robust strategies but don’t take every trade just evaluate each trade signal and determine if you want to take it or not based on market conditions.
I find trading this way and being invested in the market gives me lots of ideas to improve on the strategies I’m using or to come up with new ones.
