We've seen a lot of examples where automated traders drive the price significantly upwards/downwards.
This is more likely to happen in shallow markets like BTSX bitAsset markets.
And it is even more troublesome when you can flash-lose collateral due to margin calls.
I think providing open source bots that might be similarly configured will only make such scenarios more likely.
Regardless of that anyone with sufficient capital could drive prices upwards and downwards as he pleases in order to harvest as much collateral as possible. Note this is not fault of BitsharesX but is due to the shallow market.
Furthermore anyone with lower capital and some knowledge about the configuration of the automated traders could also try to exploit this.
I'm not saying that the system is flawed in any way. It is just young and market needs more depth.
BTW: about the depth part I'm sure crosschain trading BTC<->BTSX will do miracles. You can see my proposals about this here:
