MT4 Indicator Not Working



MT4 Indicator Not Working Fix
There have been many thousands of custom indicators written for MT4 most of which are available for free download scattered over the web, on rare occasions you will load an indicator and it will freeze the platform (see here https://community.ig.com/forums/topic/6198-mt4-not-responding/) or sometimes not appear or sometimes only appear partially.

Possible reasons for this include incompatibility, the current MT4 update is something like 1090 and some indicators written for earlier versions will not work on later versions. Also check the indicators Input settings list that arrows, lines etc are switched to True not False. There may be a missing .dll file in mt4's library needed for the custom indicator, check the dependency tab in the indicator pop up box.

If you have the source code (the .mq4 file) you can try the re-compile fix. Open the MetaEditor, double click Indicators then double click the problem indicator. Choose a number at random, change the number to a different value and press 'Compile' then change the number back and press Compile once more, look to see if the indicator is now working. The EX4. file of an indicator can't be modified and so won't appear in the MetaEditor list.
