MT4 Virtual Dealer Plugin and Suspicius Broker Activity Detection - 4xSentinel
The Virtual Dealer Plugin, by MetaQuotes (producer of the MetaTrader platform) is a nasty piece of software. It is used to intentionally delay traders' orders, in order to induce slippage. If the slippage is in the trader's favor, the trader's order is executed at the requested price instead of the better price, so effectively the broker keeps the savings. If the slippage is not in the trader's favor, the difference is passed on, so the trader loses. It is a form of cheating.
