The Use Real Values on the Options tab of most studies can be used in specific situations where the bar size doesn't use the real OHLC values of a normal linear bar. For example, if you are using a renko chart, it won't print the true high/low values for that time period. So something like a moving average set to use a high or low value would use the renko high/low instead of the true high/low. Enabling this option will use the true/high/low instead of the bar high/low.
