Value indicator on opening candle

Keith Watford 2016.02.21 23:14 #11

Does the indicator that you are calling with iCustom have a parameter to operate on Open price?

CCI has this option, so I would have thought that it is possible with the custom indicator.

Massimo 2016.02.21 23:25 #12

The indicator refers to the CCi and has no reference to the Open Price. The indicator works, but I wish that the alert was referring only to the opening of the candle. If the requirements are met, the arrow will appear that would not disappear even if more before its closure parameters are no longer respected.
Thank you, all, Massimo.

Show alerts only that Moving Average Crossover Alert [WARNING CLOSED!] Any newbie

   static datetime bar_time=0;
   if(bar_time!=Time[0])
     {
      bar_time=Time[0];
      //CheckCondition and alert if true;
     }

Something like this will only alert at the first tick of a new bar.

Hello GumRai, you have been very kind, but you have to help me still because I'm really clumsy. I set your el'alert code and the Editor does not give me errors, but does not work. Where am I doing wrong?
Excuse me, but with my skills I can not fix.
Greetings Massimo

Delete pre-alert Retard the alert several Distance arrows / candles

You cannot use the check for a new bar when looping through historical bars, it must not be included in the loop.

Massimo 2016.02.22 10:23 #16

GumRai Hello, thank you very much for your time. I corrected all the code and it seems to work. You could check if it fits?

Thanks for everything, greetings, Massimo.
