MQL4 Reference Custom Indicators SetIndexBuffer
SetIndexBufferThe function binds a specified indicator buffer with one-dimensional dynamic array of the double type. There are two variants of the function.
Call without specifying of data type, stored in the indicator buffer.
Parameters index [in] Number of the indicator buffer. The numbering starts with 0. The number must be less than the value declared in #property indicator_buffers. buffer[] [in] An array declared in the custom indicator program. Return Value If successful, returns true, otherwise - false. Note After binding, the dynamic array buffer[] will be indexed as in common arrays, even if the indexing of timeseries is pre-installed for the bound array. If you want to change the order of access to elements of the indicator array, use the ArraySetAsSeries() function after binding the array using the SetIndexBuffer() function. Please note that you can't change the size for dynamic arrays set as indicator buffers by the function SetIndexBuffer(). For indicator buffers, all operations of size changes are performed by the executing sub-system of the terminal. Example:
