iCustom Indicator - Max Input Parameters Limit

CHARLESS11

CHARLESS11  
I bought a very sofisticated Indicator that has about 150 input parameters. iCustom has a limit of about 60 something. I want to use this indicator in my EA that I am writing. However, I need to change some of the default parameters when using the purchased indicator. When loading all of the parameters, of course it gives me the "invalid parameters count" error. My question - is there any way possible to work around this max parameters limit? Only using the first 60 or so does not solve my problem. 

Thanks for any help possible!

Wow, too much inputs. I don't know the limit for the number of inputs but if that is the case, you should contact the developer to help you. The developer can add an input to get the address of a file which contains the values for the inputs. This way your EA writes the settings in a file and gives its address to the indicator through iCustom function.

  1. Limit is 63 for iCustom and 1024 in the tester.
              Does anyone know if there is a limit on number of inputs allowed in EA? - MQL5 programming forum 2020.05.06
  2. The important parameters should be first and things like color and styles last, since defaulting them changes nothing.
  3. If you need to change some past 63 rd and you don't have the source, there is nothing that can be done.

hi, is there a way to solve iCustom which is subject to an input limit;

I use a string to collect all input indicators from ea and sent using iCustom;

 string hanName= "YBM_Signaler_y19 1.0" ;
 int magixea= 12345000 ;
 //---
 int OnInit ()
  {
 //--- 
   if ( StringToTime (inpJamBuka)> StringToTime (inpJamtutup) ||
       StringToTime (inpJamAlertBuka)> StringToTime (inpJamAlerttutup))
       MessageBox ( "Action " +inpJamBuka+ " - " +inpJamtutup+ "\n" +
                 "Alert  " +inpJamAlertBuka+ " - " +inpJamAlerttutup, "BECAREFULL TIME INPUT" );

   string hanConfig=magixea+ ";" +
                    history_bars+ ";" +
                    cond_labels+ ";" +
                    cond_x+ ";" +
                    cond_y+ ";" +
                    cond_fsize+ ";" +
                    cond_fclr+ ";" +
                        
                        ..................... //Many input       
                        ..................... //Many Input 

                    ma_44_use+ ";" +                               //1__ use 
                    ma_55_use+ ";" +                               //1__ use 
                    sto_55_use+ ";" +                             //1__ use 
                    sto_44_use+ ";" +                             //1__ use 
                    sto_33_use+ ";" +                           //1__ use 
                    sto_22_use+ ";" +                             //1__ use 
                    sto_11_use+ ";" +                             //1__ use 
                    ma_crossover+ ";" +                       //MA - crossover, each MA has it's own x period 
                    piv_show;                             //__ show 

   hanCustom= iCustom ( Symbol (), Period (),hanName,hanConfig);
   if (hanCustom== INVALID_HANDLE )
       return ( INIT_FAILED );

   if (! ChartIndicatorAdd ( 0 , 0 ,hanCustom))
       return ( INIT_FAILED );


   ArraySetAsSeries (buy_buff, true );
   ArraySetAsSeries (sell_buff, true );

 //--- 
   return ( INIT_SUCCEEDED );
  }


And i Using StringSplit To Extern this String From eA Using New Input String:

 //+------------------------------------------------------------------+
 input string Ea= "" ; //Ea Config *Dont Touch*

 void QnInstallEa()
  {
   string u[ 132 ];
   StringSplit (Ea, ";" ,u);
   switch ( StringToInteger (u[ 0 ]))
     {
       case    12345000 :

         history_bars = StringToInteger (u[ 1 ]);                           //History bars 
         cond_labels = u[ 2 ]== "true" ;                           //Show conditions summary? 
         cond_x = StringToInteger (u[ 3 ]);                                     //__ x 
         cond_y = StringToInteger (u[ 4 ]);                                   //__ y 
         cond_fsize = StringToInteger (u[ 5 ]);                                 //__ font size 
         cond_fclr = StringToColor (u[ 6 ]);                         //__ font color 
         cond_line_spacing = StringToInteger (u[ 7 ]);                         //__ line spacing (pixels) 
         all_valid = u[ 8 ]== "true" ;                             //All valid candles? 
         use_live = u[ 9 ]== "true" ;                             //Use live candle? (f=completed current tf only) 
         pip_adjust_10 = StringToDouble (u[ 10 ]);                           //Pip adjustment (factor of 10s) 
         ma_all_line_up = u[ 11 ]== "true" ;                       //MA - all line up (use MAs below consecutively) 

                ............... //To many String Convert 
                ............... //To many String Convert 

         ma_1_use = u[ 120 ]== true ;
         ma_2_use = u[ 121 ]== true ;                               //1__ use 
         ma_3_use = u[ 122 ]== true ;                               //1__ use 
         ma_4_use = u[ 123 ]== true ;                               //1__ use 
         ma_5_use = u[ 124 ]== true ;                               //1__ use 
         sto_5_use = u[ 125 ]== true ;                             //1__ use 
         sto_4_use = u[ 126 ]== true ;                             //1__ use 
         sto_3_use = u[ 127 ]== true ;                             //1__ use 
         sto_2_use = u[ 128 ]== true ;                             //1__ use 
         sto_1_use = u[ 129 ]== true ;                             //1__ use 
         ma_crossover = u[ 130 ]== true ;                         //MA - crossover, each MA has it's own x period 
         piv_show = u[ 131 ]== true ;                             //__ show 

         break ;
       default :
         QnDefault();
         break ;
     }
   return ;
  }
 //+------------------------------------------------------------------+


and this result

Can Something Help me:

What part of “there is nothing that can be done” was unclear to you?

Thanks! I know this post is old but I wanted to reply back. Thanks for the info. I took a closer look at the inputs and fortunately the most important inputs just fit within the input limit. So I just left the others out of the iCustom function and it works fine. The left out inputs will just have to remain at default values. The developer does not want to revise his indicator.

Thanks!😊
Does anyone know if there is a limit on number of inputs allowed in EA?

Hi, everyone, I'm a programmer and I normally consider I know a lot of MT4 and MT5 already, but encounter something new today...
