Lot of market participants mainly High Frequency firms are exploiting the behaviors of other participants. This can be seen as a radar emitting a signal and listening just after the echo. So know that also financial markets can be exploited like that. Smart algorithms can send small or big size orders like a radar sends signals and listen the echo from other participants. Once it is done enough time, a prediction model will be able to detect a pattern from the orders sent and exploits this pattern for getting high alpha execution. Of course this can be done by a firm which is able to loose money for building its algorithm. Cash and Time are what Drive financial markets.
