Agreed, but if I put say 'Never create a ping with qty > than 4' than will create smaller orders up to 4 each time.

This means that Ping orders will be created 4 units each, until nothing left in Buy pool/

example
Start Buy Pool = 2 BTC
Market ETHBTC, price 1ETH = 0.1BTC
Maximum ETH to buy = 20 ETH

With above suggestion, i will end up with  5 orders with 4ETH each, which is fine now.

The Pong trade completed with 0.2 Gain, the Buy Pool now = 2.2 BTC

The new Ping orders being created will be 6 , at 5x same price 4@0.11, and 1x order 0.2@0.11

This is not dynamic.

The aim was to have the Buy pool being split Smarter, by using Fixed or increment% in Qty, and Fixed or increment% in Price, a bit like the Advanced Panel does.
During this split operation CAT looks at the 'Never create a ping with qty > than ' condition in Pool setting, if agrees creates the qty calculated, else puts the limit as per Pool setting.

I guess this way you keep the Buy pool split at each and every new run, creating smaller orders.

Does this make sense?
