High volume, Discounted brokerage - intraday Options

looking for information on
High volume, Discounted brokerage - for intraday Options trading.

I tried with “Kotak Neo”
Their Neo app looks very dangerous

what i understand, the bought price is much higher than the price when we place the order. If the price difference is < 1 rupee, it can be understandable.

But, when the difference of the price is in 2-4 rupees/share, that too in option lots, we’ve to doubt about the genuinity of the broker.

Did anyone face similar problem?
