Can't deny, the whole market already turned into reddish but its hard to say that, this is really bearish trend or not. but i think market is passing through correction period cause we have been seeing the bullish market for long. well i except soon market will be back on its green line soon within few days. If not and stay long as 20 days something as you said, then can be considered as bear market
If it now goes down for 20 days then we are for sure in a bear market. However, after that maybe it'll be already over again. Nobody can predict the market anyway, so put your money where you think it's invested best and don't put all your money into a single position, but spread it out as good as you can. We will have some market turbulence ahead for sure.
