What is data filtering?

This is another way for broker to cutt off your profit and increase your losses. The raw data that comes from real market sources like ECN (electronic communication network) are processed by trading server in such manner that rare moves are suppressed and overall output stream looks smoothed. The fitering ability is advantage from brokers point of view and the software developers advertise this feature and do everything to satisfy their clients. Do not forget, those who pay money for server and client part of Metatrader or another platform, call the tune. Definitely they are not you and me but our brokers. This is why most mechanical trading systems unable to function normally on short time frames like ticks or minutes.

Have you ever seen the place where your rainbow financial dreams become ash and cinder? If not, look at the fragment of MT4 server Administrator Panel. From here the broker's admin can cut the tails of your winning candles. He can do almost anything to stop your EA getting profit if you start to win too much.
