The most common issue here (aside from not being installed properly) is that MT4 broker delivers its symbols with a prefix or a suffix. You can check this in your Market Watch. This is often not obvious, and can sometimes be a simple full stop, a colon, semi-colon or letters. Sometimes these include number as well. For example EURUSD,H1 is the standard but EURUSDpro,H1 has a suffix after the currency of “pro”. If so you will need to add this to the user inputs for the currency matrix to work correctly
To fix this please open the indicator’s Inputs tab and scroll down to find the Currency Suffix input field (or Currency Prefix if the extra characters appear before the symbol). This is the variable field that you will need to update, if your FX broker delivers your currency pairs with a suffix. As an example this might be EURUSDm, in which case you would need to enter the value m in the currency suffix field. If your currency pairs are delivered with a suffix, then you MUST enter this in this field, otherwise your indicator will not work.
