Help with Indicators Which Seem to be freezing my MT4

Good morning everyone,

I hoped someone might be able to help me. I use the indicators in the attached link

There are 3 indicators attached: stochastic rainbow, trend signal and ATR levels. I find that, after attaching these indicators, my MT4 freezes after a number of days. I am not sure which is the culprit but I think it is the trend signal.

I wondered if someone could help me to identify if there are any bugs that need fixing and how to do it.

Many thanks in advance,
