Strategy and indicators integration

[afoschini]

Hi,

I have coded a simple indicator that uses an additional timeframe series and then calculates and plots 2 levels, and now I am in the process to code a strategy that make use of these levels to trade.
Is it a better practice to reference the indicator from within the strategy (myIndicator.mylevel) or is it better to re-implement the indicator inside the strategy OnBarUpdate() method and make use of it locally?

Thanks, bye

Hello afoschini,

Thank you for the post.

This would really depend if you want to reuse the indicator in other scripts. Generally isolating parts of your overall logic into indicators can help in reducing the size of the strategy but this all comes down to your goals. If this will not be used anywhere else, it may be easier to just place it in the strategy.

I look forward to being of further assistance.

Thank you Jesse

I was speculating about possible sync problems between calculation in the external indicators OnBarUpdate method and the strategy OnBar... method.If as I undersyand from your answer this is not the case, I will surely go for the flexible approach.

Hello afoschini,

Yes, the indicator being called should assume the host's properties or the strategy in this case. This should entail that the indicator is in sync with the strategy as it is called by the strategy. In both cases, you should be able to sync the calculation, either in an external indicator or directly in the strategy.

I look forward to being of further assistance.
