I've got a question. 

I am trading on a pair with little liquidity. This means that even little orders can have large upward and downward effects on price.

What happened is that after a successful buy ping-pong cycle, the price shot up suddenly and CAT did the following buy ping at a very high price. Then the price went down a lot, so I made a loss.

Except than a stop loss rule, are there other ways to set CAT so that on a successful buy ping-pong, the next cycle starts only if the next buy price is lower then the previous ping buy price + %.

I hope I've been clear enough.
