Is there a way to make your Indicator re-calculate on every bar or minute rather than each tick?

Hi Guys/Girls,

 

I read on here that the Ontimer functions only work for expert advisors. Im having some trouble with running my EA/Indicator combo where things are over calculating for instance I have an automatic Fib indicator. source below.

This needs to be dynamic incase bars drop off outside the range or a new high or low is set as its an important part of my reversal Entry EA.

However this Re-draws its whole fib scale on every tick which really isnt needed. I use the EA and the Indicator on the H4 chart and really it only needs to be re-drawn if the current bar is breaking the Ihighest Bar or Ilowest Bar value and on every new bar. It wont change unless either of these 3 elements are effected but at the moment it re-draws on every tick.

 

Any Suggestions? at the moment running this on say 20 pairs is killing memory and slowing down the terminal no end and for absolutely no purpose.
