Requesting assistance with coding an indicator and EA for trading signals.

traderduke:
You would use 1 2ma for overall trend and another for short term highs & lows re-entry.

Does that mean that there should be two volty channel indicators?

Hi coders.

I need an help on this question: how to shift horizontally arrows signals of a simple ma cross indicator?

I tried this but it shift only on the left, i need even on the right.

Thanks

Questions: to start with Indicators with alerts/signal Help... how do I

Thanks

Did you try shifting the buffer instead of shifting the single value

Something like :

   SetIndexShift(0,arrowHshift);
   SetIndexShift(1,arrowHshift);

And then revert these lines to have no shift at all

//
// instead of 
//


         if (trend[i] == 1)
               CrossUp[i+arrowHshift] = Low[i]  - arrowsDisplacement * gap;
         else  CrossDn[i+arrowHshift] = High[i] + arrowsDisplacement * gap; 

//
// it has to be
//

         if (trend[i] == 1)
               CrossUp[i] = Low[i]  - arrowsDisplacement * gap;
         else  CrossDn[i] = High[i] + arrowsDisplacement * gap;

PS: to shift the values now you have to use + values to shift the arrows to the right and - values to shift the values to the left (attaching the test code and it works OK for any case of shifting the arrows - left or right)

Does that mean that there should be two volty channel indicators?

mladen

Sorry for not answering sooner, I was hopping to come back with a solution to the indicator question but that didn't happen

Yes, that's correct. sorry for the misunderstanding. I was answering steven about the 2MA indicator. I was unable to use the existing indicator for both entry & reentry as MR Tools did for the PrCh indicator, though my EA could never get the reentry correct, It like swing at smoke.

Anyway I can do it in the EA with 2 voltys so no need to create this indicator.

Thanks for the help

Hello.

I´m trying to make an alert based on shved supply - demand indicator in accordance with stochastic crossover. I am informed that this indicator can be used to crate EA´s since it stores info in buffers however i am not super confident reading and understanding mql4 yet and has no mmore then 2-3 month of experimentin time.

Therefore i hope someone out there could help me write the iCustom line to check wether the price is within zoene or not.

Do something like this (check the comments too)

   //
   //
   // checking if the price is withing the lower zone
   //
   //
   
   if (Close[i] <= iCustom(NULL, PERIOD_CURRENT, "shved_supply_and_demand", 6,i) &&
       Close[i] >= iCustom(NULL, PERIOD_CURRENT, "shved_supply_and_demand", 7,i))
   //
   //
   // checking if the price is withing the upper zone
   //
   //
   
   if (Close[i] <= iCustom(NULL, PERIOD_CURRENT, "shved_supply_and_demand", 4,i) &&
       Close[i] >= iCustom(NULL, PERIOD_CURRENT, "shved_supply_and_demand", 5,i))
       
   //
   //
   // PS: that indicator stores values only for current bar in the buffers, so it works only for i==0
