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.
Crystal clear. Yes, you can (I would say you should) set a Price Limit to your next Ping, both as an absolute value or as a percentage. The form to create limits is very flexible, you can define whatever you need.
Never Buy/Sell Under/Over your last Ping/Pong Buy/Sell +/- x%.
In fact, it would be almost impossible to make a profit with CAT without setting the right price limit, unless a) the price is moving in just one direction or b) you let CAT do just one pin-pong.
Btw, a Stop Loss rule only affects Pong orders, never Ping. Thats what Price Limits are for.
