Correct Setting for calling yesturday close

[MJUK10]

I'm using the following code to call the close of the previous day. The period im calling is a daily bar saved as bar array 2 and the primary data is intraday 1 minute. I have set the number of bars back to [0] believing that the last daily bar is yesturdays bar until the current intraday sesison ends. Is this correct? Or should I have been using [1]? Is there any difference when backtesting v live trading?

Thanks

Mark

&& GetCurrentAsk() < (Closes[2][0] + (ATR(BarsArray[2], 8)[0]))

Mark, the easiest way to get yesterday's close would be to use the PriorDayOHLC indicator and just call the plot of yesterday's close.

double prevClose = PriorDayOHLC().PriorClose[0];
