For all beginners need to know how currency strength is read in general by any indicators or EAs:
At first it is important to have all 28 currency pairs in the market watch. The indicator need this data to calculate strength. Then you need to know about mt4 how it update history. Only when a pair and TF is requested mt4 history will be updated. So if you change the TF on the chart were the indicator is on, mt4 needs first update all the history of all pairs. This take a while (like 10 to 30 seconds? It depends of your internet connection.). Now you need to change the TF again and back to it and all currency strength will now show correctly. This is not a repainting but mt4 need to update the history. THis needs to be done at start of mt4 when your account is connected and every time when you change a TF. Yes it make some work but there is no way around, mt4 works like this, unless you have multiple charts for the required TFs always open then it is only one time (for every TF each) when your mt4 is started.
Happy pips
