Very nice, thanks!

It seems that the code of this indicator is not complete or some parts was removed: IE "double dSellBuffer[]" is declared but never used...

Any suggestions?

Initially it was used to mark the exit points on the chart, but I guess they were excessive for this indicator as the arrows themselves are enough for that.

Thanks for the info!

Any Advisors based on this Indicator available?

The CCI Arrows indicator was updated and is now available for MetaTrader 5.
Seems that there is also a bug in MT5 regarding the arrow width.
If you use the indicator alone the width is correct, together with other indicators the width is always small and cannot changed.

I tried to plot the current CCI value on the chart with this method
...
ObjectCreate(0, "myCCInow", OBJ_LABEL, 0, 0, 0);
ObjectSetString(0, "myCCInow", OBJPROP_TEXT,"CCI @ "+DoubleToString(myCCInow,1));
ObjectSetString(0, "myCCInow", OBJPROP_FONT, font_face);
ObjectSetInteger(0, "myCCInow", OBJPROP_FONTSIZE, font_size);
ObjectSetInteger(0, "myCCInow", OBJPROP_COLOR, White);
ObjectSetInteger(0, "myCCInow", OBJPROP_CORNER, corner);
ObjectSetInteger(0, "myCCInow", OBJPROP_XDISTANCE, 1+distance_x);
ObjectSetInteger(0, "myCCInow", OBJPROP_YDISTANCE, 1+distance_y);
..

unfortunatly it does not return a value which makes sense. Is there a bug in code?

Do you see the value on the chart, but it doesn't make sense? What kind of values do you see?
There are displayed various switching values, which do not match the current true readings of the standard CCI indicator in MT5.
The arrows are displayed correctly though when the zero-line is crossed.

If I do the same in MT4, it works correctly.

I can't say much without seeing a screenshot, but I see 2 potential problems in your code:

1. If you call that code in OnCalculate() function then you create an object each tick. Do you delete it each tick? It's better to create it only once and then only change the displayed value.

2. You have a variable containing current CCI value and the object with the same name - myCCInow. Ideally that shouldn't be a problem, but maybe it's the cause?

Thanks for the advice. I changed the name of the objact and the position of the inserted code, it's now inside on the OnCalculate but directly above the

...
return(rates_total);
...

line.

Works now properly as far as I see it.

I think that you can greatly reduce the indicator's load by placing this part of the code in the OnInit() function:

ObjectCreate(0, "myCCInow", OBJ_LABEL, 0, 0, 0);
ObjectSetString(0, "myCCInow", OBJPROP_FONT, font_face);
ObjectSetInteger(0, "myCCInow", OBJPROP_FONTSIZE, font_size);
ObjectSetInteger(0, "myCCInow", OBJPROP_COLOR, White);
ObjectSetInteger(0, "myCCInow", OBJPROP_CORNER, corner);
ObjectSetInteger(0, "myCCInow", OBJPROP_XDISTANCE, 1+distance_x);
ObjectSetInteger(0, "myCCInow", OBJPROP_YDISTANCE, 1+distance_y);

And this one leave in the OnCalculate():

ObjectSetString(0, "myCCInow", OBJPROP_TEXT,"CCI @ "+DoubleToString(myCCInow,1));

Yes, you are right, this is even better.
Thanks.

is it possible to get the arrows from the calculation based on another timeframe.

i.e. can I have access to CCI values of other timeframes by writing

int myCCI = iCCI(NULL,TimeFrame, CCI_Period, PRICE_TYPICAL);


?????

Yes, why not?
Thanks for the reply

I tried a multitimeframeversion of this indicator

my code is as follows

The result is as shown in the picture.
Is there a mistake in my code?
