Crude trading is much different than equity or nifty fno.
Where equity in its uptrend/downtrend can keep on moving up/down for days without major retracement but crude while on its strong uptrend/downtrend can go for big retracements.
Crude oil is called beast. Its complete day behaviour is difficult to fathom because crude oil is related with many events/criteria and timing. Support and resistances play very important role here. We should know what the crude is doing in its hourly/4 hour/daily charts. It will give ideas to day trade.
But, whatever we know, crude oil demands more. Perhaps thats why it is called Beast. It requires experience to day trade it. So start with mini 1-2 lots only. Dont go higher. Because I know it will take much time(even years!) to master it.
Best of luck !
