Bars and Rates Information Utility, displays how many bars there are in all timeframes for any user selected symbol, and shows the 'CopyRates' information availablity for any bar:
This utility is not a trading or market information utility. This will likely only interest those writing (or debugging) indicators using multiple timeframes and collecting information using Bars (or iBars) and CopyRates. The utility creates a list showing the number of Bars reported by the "Bars" function and shows the success of CopyRates for any selected bar by displaying that bar's time from the collected data (or, it shows the error).
