i think the more compressed range the more wide range we see after breakout.
that doesn't tell us that it will give us next wave of 300 pts / 500pts. How long that expansion will last depends on many other factors so we should not anticipate bigger expansion.
eg - if mkt breaks upward on Monday, It may not be able to go too far cause, it has already travelled 700 pts in current wave. Still 100 to 200 pts is possible. If it breaks down on Monday then support zone are quite far away (4000/3900 level).. It might be able to go down to those level or it might find new buyers before that..
Lets not anticipate that and listen to the market and adjust our trades.
Happy Trading
