Hello

Everything's fine?

While making the code for the use of iAlligator(), I realized that the code could be optimized on copying data to buffers

My code for the Alligator in codebase 

The correction is done on this part

   if ( CopyBuffer( g_ptIshimoku, 2, - g_kijun_sen, rates_total, g_BuffSenkou_Span_A) < 0)
   {
      PrintFormat("Error retrieving data for SENKOU A");
      return (0);
   }
  
   if ( CopyBuffer( g_ptIshimoku, 3, - g_kijun_sen, rates_total, g_BuffSenkou_Span_B) < 0)
   {
      PrintFormat("Error retrieving data for SENKOU B");
      return (0);
   }

And specifically on these 2 copybuffers that are shifted to have the illusion of a prediction.

In this syntax, at each pass, all the history is copied into the buffer, while only a new bar is added. 

That's too bad

Optimization is quite simple.

We form a loop that will go through the entire history with the right positioning thanks to Oncalculate's system constants

        /* Copies of new bars only */
        for(int i = prev_calculated;i < rates_total; i++)

et de changer les copybuffer
                        if ( CopyBuffer( g_ptIshimoku, 2, i - g_kijun_sen, rates_total, g_BuffSenkou_Span_A) < 0) 
                        {
                           PrintFormat("Error retrieving data for SENKOU A");
                           return (0);
                        }               

                        if ( CopyBuffer( g_ptIshimoku, 3, i - g_kijun_sen, rates_total, g_BuffSenkou_Span_B) < 0) 
                        {
                           PrintFormat("Error retrieving data for SENKOU B");
                           return (0);
                        }

This syntax only copies the new bar, which saves resources and speed.

Don't forget to put stars for the SEO of my code

Hello to all, Thank you for your valuable work. A question: How can I fill the space in the cloud - like the indicator used in Metatrader - with dots? (instead of solid color) Thank you.
