Every dip will be good buying opportunity , if anyone feels he don't know trading can go for SIP in nifty etf chart says long term plan is higher , short term is downside may be upto 17k or 16k from there expecting a good bounce ,April or May will give clear way since then buy on dip , weekly basis cup handle type or inverted h&s formation in progress once it's done we will see sharp move , but no idea for big investment just SIP which u don't feel worthy , it's my personal view your money your decision
