Situation around MetaTrader5 is unclear right now, it doesn’t have big customer base and most brokers are still not offering it.
MetaQuotes (company behind MetaTrader) finally seems to accept that EAs should be backwards compatible, and in the newest MT4 build 600+ they introduced a “mixed” approach, where it offers new MQL language features from MT5 while being backward-compatible with MT4.
So it seems that in the future MT4 and MT5 platforms will merge into one.

If there will be significant demand for MT5 support in the future of course we will add this export option to SQ and EA Wizard.
