Why last traded quantity is changing during circuit limits? During upper circuit limit, there will be only bid price, then how the quantity will trade during that time?
Anytime seller can come and sell. But it may not show in market depth because it may happened in a milliseconds duration.
In upper circuit, only buyers will be there, so anyone holding those shares can sell their holdings at the upper circuit price (either by market order or by limit order). Upon doing so, the pending buy orders of that quantity at the upper circuit price will get filled. Upper circuit (or lower circuit) doesn’t mean that trading has stopped for that scrip.
