As per chart formation...no indication as such...
Hence.....use the swings and trade....swing may be 4500 + points...this swing is good enough to make good money....
(Check "Main Aqua One" sheet of Sishyan and read the chart at your end)...
If you are a investor, then only, you should worry about the crash....
For a option trader, if you are able to understand the swing reversals, you will never ever be caught in any market crash for sure.....
This is just for information purpose....nothing to do with our option trade...
