Questions from a "dummy" - page 156

progma137:
Thank you. It worked. I declared this variable as a global variable.

Right.

But keep in mind that LWMA needs to have one of these variables each for parallel LWMA calls. As many different parameters in LWMA, so many variables

[Paladin80]

How do I close a position (which is the sum of several open positions)? Is there an analogue to OrderClose(), or should I open a position in the opposite direction?

You open in the opposite direction with the same lot for which the position is now open.

The result will be "no position".

Any position in any instrument is already the sum of all previous trades.

ZZZY Remind that a position on any tool can be only one or not exist at all.

Thanks, I'll keep that in mind.

And I have the following question.

can I add a custom indicator into OBJ_CHART and if so, how?

[---]

progma137:

can a custom indicator be added to OBJ_CHART? and if so, how?

ChartIndicatorAdd ?

[Viktor Vasilyuk]

sergeev:
ChartIndicatorAdd ?

error 4802 indicator cannot be created

My custom indicator, put separately, works.

[---]

progma137:

error 4802 indicator cannot be created

Then find out why it cannot be created.

and only then proceed to adding it to the chart

[Viktor Vasilyuk]

sergeev:

then work out why it's not being created.

and then move on to adding it to the chart

subWindowHandle = ChartWindowFind();
   Print("Номер подокна " + subWindowHandle);
   no = "name_object";
   // 2. создаем объект график
   bool isFlag = ObjectCreate(0, no, OBJ_CHART, subWindowHandle, 0, 0.0);
   if(isFlag){
      ObjectSetInteger(0, no, OBJPROP_CORNER, 0);
      ObjectSetInteger(0, no, OBJPROP_XDISTANCE, 0);
      ObjectSetInteger(0, no, OBJPROP_YDISTANCE, 0);
      ObjectSetInteger(0, no, OBJPROP_XSIZE, 500);
      ObjectSetInteger(0, no, OBJPROP_YSIZE, 200);
      ObjectSetInteger(0, no, OBJPROP_PERIOD, PERIOD_H8);
      ObjectSetString(0, no, OBJPROP_SYMBOL, "GBPUSD");
      
      //int handle_ind_h8 = iCustom("GBPUSD", PERIOD_H8, "Examples\\MACD", 12, 26, 9);
      //int handle_ind_h8 = iMACD("GBPUSD", PERIOD_H8, 12, 26, 9, PRICE_OPEN);
      int handle_ind_h8 = IndicatorCreate("GBPUSD", PERIOD_H8, IND_MACD);
      bool f1 = ChartIndicatorAdd(0, subWindowHandle, handle_ind_h8);
      Print(GetLastError());
      
      ChartRedraw();
   }

it's not drawing:(

[Dmitriy Parfenovich]

progma137:
It does not work:(

Does it not work with iCustom either?

1. you must have the wrong currency pair in the tester

2. Wrong timeframe.

If the tester has an indicator, everything is OK.

For visualization in real time, we have to add ChartIndicatorAdd and ChartRedraw .

Doesn't the iCustom also work?

1. you must have the wrong currency pair in the tester

2. Wrong timeframe.

If the tester has an indicator, everything is OK.

1) This is not a tester. I just create a chart type object in a separate window through the indicator

2) Here all timeframes are taken into account.

As for the visualization - don't I have it?
