I have a short experience with Algo trading but not a very pleasant one. I read recently that operators know when algos will be triggered to give directional calls and when stop losses will get triggered. So they will first drive up the prices and then quickly move the prices down to trigger the algo on the wrong side. Hence it's quite often that stop losses get triggered soon after which the stocks move back in the right direction again.
Is that something the others have also experienced?
