If Retracement levels will come(with Corrective pattern) then it will be a buying opportunity with stop loss of 10622. This retracement levels will change according to new fresh high of tomorrow.
If impulse started from 10494 is wave C then it will not go much higher above 10780.
If impulse started from 10494 is wave 3 then ...
It seems wave (A or 1) is completed at 10565 and retracement levels for wave (B or 2) are given in chart. which can be used as buying zone with stop loss of 10333 which is of almost 100 points so plan your trade by analyzing wave pattern on live chart tomorrow. Good luck.
Here in this chart wave (5) and wave (v) will be in extended zone after breaking 10486 and 10408 respectively. Maximum range of both waves is coming at 10351-10325. so after completion of both wave Nifty can bounce up to 10543 and further it can also extend to 10700.
Most probably one impulse wave is completed from 10774 to 10512. and we can consider it as wave (A) and now retracement levels of wave (B) is coming at 10612, 10643 and 10674 which can be achieved in coming sessions.
I would suggest not to trade for wave B in options and wait for wave C to trade.
If Nifty decline from present ...
Starting from 10334 it seems currently we are in (iv) of (C or 3). wave (iv) retracement level 10740-10693 can be buying opportunity with stop loss of 10655(Not so accurate). From that buying range nifty can bounce up to 10838 and further it can also extend up to 10865-10941.
DO NOT PANIC IN SITUATION
20th Nov 2018 and 21st Nov 2018 fall in NIFTY occurred due to correction and profit booking
Important support around 10600 and 10550
If NIFTY holds 10620 it may move towards Resistance 10655, 10685 and then 10720 onward and also rally upto 10815
in the next week expiry NIFTY may even move towards 11350
Nifty have not achieved minimum target of 10666 which can be achieved in coming sessions. Even if nifty failed to achieve 10666 and came down then 10526-10444 is support range and from this range again Nifty can bounce to 10666 and above. Down side reversal is only possible below 10444.
