Does it exist any similar behaviour in MQL4? This code throws the error 'array out of range' in the Close[bar] expression and I cannot handle it properly. Any help will be appreciated. bool isBarClosed( int bar ) { bool barClosed = mql4 error code true; double closePrice = Close[bar]; int error = GetLastError(); if ( error == 4202 ) { barClosed = false; } return barClosed; } algorithmic-trading mql4 metatrader4 mt4 share|improve this question edited Nov 10 '15 at 0:10 user3666197 7,79921330 asked Aug 24 '15 at 11:20 webmeiker 41621030 Isn't there an official documentation? –m02ph3u5 Aug 24 '15 at 11:21 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted No. MQL4 has no syntax support for a construct alike a try/except/finally or try/catch use-case in python / java and alike languages. How to handle exceptions? Assume there are no compile-time errors. The run-time errors are hard to be handled, some even cause the software to crash. One could and rather shall proactively sanitize the MQL4-code with a due type-checking and use-case pre-validations so as to prevent exceptions. Exceptions to this are dbPool operations, which may, under some conditions, "legitimately" fail to yield an expected result. A GetLastError() ( if it was cleared a-priori the exception itself ) may serve as an almost-post-mortem identification, not as an exception handler. 4202? Not your
