Custom Indicators and Computer performance

[mrw]

Hi,
Some background: I have some basic experience creating and using custom indicators. I have noticed that some custom indicators I have built seem to slow down computer performance. For example I sometimes see that there is a noticeable delay/lag in price when comparing two charts that differ only in which custom indicator I have added.
My questions:
1. Would it make any difference for computer resource utilization to break a long/complex custom indicator into multiple smaller ones when possible?
2. Would it make any difference for computer resource utilization to reference other studies (example MACD) vs just including the MACD code in my indicator and referencing it directly?

Thanks in advance!

Referring a Build-In is recommended for performance improvement, AFAIK there is no way to refer a custom indicator in another custom thought.

As much as possible assign values to variables than running calculations on values, even if the values keep changing.

Ex: instead of using High, Low Close multiple times in the script for various calculations, do something like the following.

def o = open;
def h = high;
def c = close;
def l = low;
    
def con1 = O - L;
def con2 = O - C;

Okay thanks for that advice. I appreciate your input.
