draw rectangle each minute on M30 candles

[pkoral]

Hi

I have bars M30. I want to draw a rectangle on each minute of this bar. As start I want to draw bid prices using rectangle. 

My code:

MqlRates prices[];
datetime lastTime = 0;
double lastBid;
int toCopy = 3;
void OnTick()
  {
   if(CopyRates(Symbol(), Period(), 0, toCopy, prices) == toCopy)
     {
      double bid = NormalizeDouble(SymbolInfoDouble(_Symbol, SYMBOL_BID), _Digits);
      datetime currentTime = TimeCurrent();
      if(lastTime != 0)
        {
         string name = "bid" + nameCounter;
         ObjectCreate(0, name, OBJ_RECTANGLE, 0, lastTime, bid, currentTime, bid);
         ObjectSetInteger(0, name, OBJPROP_COLOR, clrRed);
         nameCounter++;
        }
      lastTime = currentTime;
      lastBid = bid;
      //Print("currentTime=", currentTime, " bid=", bid);
     }
  }

The result is in attachment.

Which means I can't draw rectangle (or other object) with resolution 1 minute.

How to set possibility do draw an object each minute without changing candle length?

The bar already represents the bid prices

How is that? During M30 bid price can change dramatically. And bar (candle) has OHLC prices (4 prices).

1. There is nothing related to 1 minute in your code, it's executed each tick.

2. You need to set your terminal chart setting.

So what you want to create 1 minute bars ? Just use the 1 minute chart

And if you’re are trying to display just 1 m1 bar then all you have achieved is an extra 4 prices OHLC of the minute it’s not clear what you are trying to do
