MT5 Previous Bar Hi-Lo

New comment
 

Does anyone happen to know how to convert this to MT5 so I can display the previous bars' high and low:

 

int counted_bars=IndicatorCounted();


double HIGH;
double LOW;


if((Time[0]!=curTime))
{ 
curTime=Time[0];

HIGH = High[1];
LOW = Low[1];

I've tried numerous things but can't seem to find a solution.

 

You can use CopyRates() function to get time, high, low,... values.

This code is written without check in compiler, therefore you probably will need to fix some small errors:

int counted_bars=IndicatorCounted();
double HIGH;
double LOW;
MqlRate barData[];
int copiedAmount = CopyRates(_Symbol, PERIOD_CURRENT, 0, 2, barData);
if (copiedAmount == 2){
   ArraySetAsSeries(barData, true);
   if((barData[0].time != curTime)){
      curTime = barData[0].time;
      HIGH = barData[1].high;
      LOW = barData[1].low;
   }
}
 

Here is the implementation in the indicator:

You guys are the best! Thank you so much, I've been struggling with this for days. Thank you.
