I know a strategy has an option to use the minimum bars, however NT7 only does this for the first open.

Is it possible to use some kind of indicator to prevent a strategy from trading before a certain number of bars has elapased?

I think the problem here is that you need an indicator training period, before you can rely on indicators to execute trades. You should therefore code your strategy in a way that

-> indicators are trained during the first N bars
-> and that trades are only executed once the training period has been completed

I typically use two start dates. The first start date for the indicators, and then the second start date for trade execution. I have serialized the start date allowing me to enter two dates in the dialogue box for the strategy.

I am not sure if this helps answer your question, but there is a variable "CurrentBar" built into NT7. This starts out as 0 and increases with each additional bar, so a simple test could be:

if (CurrentBar<50)
return;

Put this at the start of your OnBarUpdate() function and the first time the rest of the code will be executed is on the 51st bar.

Here is the NT7 reference page:

No problem, one of the reasons I like NexusFi (formerly BMT), it saves me LOTS of time while coding. Someone on here has almost always solved the problem before me. Good luck.
