Trading Signals Coming to MetaTrader5
by Ron Finberg at Forex Magnates
With much of the online retail forex trading world being fully entrenched with MT4, the upgrading process for brokers to MT5 has been pretty slow. Of major brokers, only Alpari has launched an MT5 offering. Slowing down the upgrade process has been changes in the platform’s programming language MQL between MT4 to MT5. The result is that traders using custom indicators or EAs for MT4 will need to rewrite their scripts to utilize their strategies in MT5. As such, with the lack of a “hot” indicator hitting the market for MT5, there just hasn’t been much demand from clients for the upgraded platform.
