For questions related to Freebase's Metaweb Query Language. Please use MQL4 and MQL5 for questions related to FOREX MetaTrader Terminal platform MetaQuotes Language.
Disambiguation was needed, as the MQL
tag is, unfortunately, used for two different things:
The Metaweb Query Language which is a
JSON
query-by-example style language used to query Google'sFreebase.com
MetaTrader Terminal platform programming language developed at MetaQuotes, Inc., under a code name
MQL4
andMQL5
programming language. These compiled, c-like languages are used for complex control of the MetaTrader Terminal software used in Terminal/Server relation for foreign exchange trading, derivatives trading and commodities trading.
Most, but not all, StackOverflow questions relate to the first context of use.
For the sake of the second, rather use MQL4
or MQL5
respectively.
