Are Call premiums getting 'managed/manipulated' ??

Are you also seeing this?

Giving the call prices for 18900 Calls for Tomorrow's expiry -

9:33 AM, Nifty@18625, 18900 CE @9.1
9:44 AM, Nifty@18638, 18900 CE @9.1
10:19 AM, Nifty@18655, 18900 CE @9.1

And it's not like the time difference is so huge that time premiums dropped ..

Did you notice call price remaining at the same level even though the index moved up 30 points

At the time of this posting, index at 18661, 18900 CE @9

Is this a 'free market' where prices are determined by demand supply?
or
is this a market 'rigged' and 'managed' by big players?

And how long will this keep continuing??

This may look like a rant, but ..

Comment:

Almost all of us in market think that big players control the market, but at least there is should be 'some room' to trade, some space to react. look at the price squeeze shown above..where is the room for anyone to get out??

..and this control shouldn't look like 'outright manipulation', and done such publicly right?

I understand this is a far out-of-money option, but who among us knows what will happen rest of the day and tomorrow? Except for those 'big' players if they exist at all..
