Quote Flow Monitoring

Many MetaTrader 4 brokerages are experiencing problems because they are unable to find out when quotes have stopped flowing on a symbol. When this happens, ill-intended traders take advantage of a frozen feed with old quotes and place off-market trades, which are always 100% winners.


To prevent this unpleasant situation, Boston Technologies created an Expert Advisor that any one can run in their MetaTrader 4 Client Terminal. This Expert Advisor detects frozen quote feeds and informs the user, with both a visual alarm and a sound alarm, that quotes have not been received on a given symbol.
