You can try this way

You can set a % GAIN OF 999 so pong will never ben completed
Remove option ALWAYS CREATE ORDERS FROM TRADES.

And C.A.T. won't create any PONG.

Then.

You can set a BUY/SELL Pool high value (Value is in total, you can have a preview of new order calculation) and you can limit with option "Stop Ping Creation if total orders amount is > X"
You can set Never Create Ping with Quantity > Y

Result will be very similar to the one you ask me.
