i do intraday trading in nf-bnf options only buying using finvasia.i am trading in 8 accounts simultaneously n profitably.
as far as strategies or systems my advice to you just use simple nf-bnf's support n resistance n price action n patterns like double top/bottom Head n shoulder and trade that using options.its enough to make very good amount of money.plan your trade in advance.never take trades in hurry.dont over trade n don't trade anywhere in charts.
