bist100 is showing topping signs (collapse is possible )

in spite this index has respected 100d SMA until now, meaningful divergence in RSI is visible in weekly time frame.
there are a lot of leaders that are showing stage 3 and some of them are moving towards stage 4 (declining)
no one can predict the market .
but , a big collapse in BIST100 is possible.
I don't sell(short selling) in this situation . But I am going to be cash in this market for now.
