I have a lot of MT4 indicators and overlays on my platform. Is there a way i can reduce the amount of history each indicator covers when i scroll back the charts? Would this help?

I solved that problem by eliminating all indicators from my charts. Way faster now!
You are in a maze of twisty little passages, all alike.

Most items can be modded to include a Maxbars input.

But more importantly look at how much history that you are actually loading. i only load 5000 bars max. In Tools....Options..Charts..use 5000 for max bars in history and max bars in charts

Hmm you can code a simple barcount logic function into the indicator itself.

At the top portion of the indicator's coding (the place where you declare all your variables and imports etc):
PHP Code
extern int BarCount = 1000;
int i;
Place this within in your start function:
PHP Code
int start()
{
   i = BarCount;   
   while(i >= 0)
     {   
         //This is the place where you will add your indicator logic functions
     }
   return(0); 
}
There are also other ways or doing this.

If you are using "for" loops instead of "while" loops then just use limit=BarCount in the above example.

you can calculate the number of bars that appear in your indicator window and just draw them any bar that doesnot show in the window are not seen, usable, nor drawn. (screen shot 1)

If you scroll the chart to the left to see more data you first get an empty space in the window. (screen shot 2)

On the next tick the missing data will get filled in to fill the empty space. (Screen shot 3)

When you scroll back to the right the data that was added is then removed. Only the data that is visiable is shown. However no data to the right is ever removed even if it is not visiable, as one would assume that the chart will be scrolled back to the right edge again, for trading.

edit: I added a forth screen shot to show how one can change the indicator parameters on the chart with out going to the dialog box. when you mouse over one of the parameter inputs it light up (light blue) and a row of numbers will show up. The first one is the current setting, the rest are the new setting entered with up or dn arrow keys to increase or decrease the number by, next is the minimum that it will accept, following the maximum, and then the default setting. when the mouse over event ends the parameter is changed to the new setting. Note my mouse doesnot show up on screen shots it is however over the 'periods' on the chart.

Screen shot 4 also shows that as more bars are added to the right edge of the chart, data is removed from the left.
