I'M not considering today's i.e. 2-3-2024 candle/trading as the levels wont work.
so 620-621 a hurdle can say a small resistance & 585/595 support, & if gap up opens wait till 10am for price movement if down can sell or if taking support can buy, if flat open then wait for level break & in gap down same wait till 10am for price movement.
so levels are 615 below(aggressive traders) 614/613.60 below (safe traders) can try for sell for 612-610 tgt levels=flat scenario
621 above 15min candle closes & green candle for buy for 623.80-624.60/625.15 tgt level can be seen=flat scenario.
