Help for a MT5 indicator

MQL5 Indicators Experts

Specification

Hi,

I have created an indicator that draws simple arrows on the chart and implemented a KNN calculation. However, I'm facing 2 issues and looking for someone who could help with it. 

Errors should be easy to resolve, but at this point I'm blocked and don't have much time right now:


Errors:


'data' - invalid array access

'[' - parameter passed as reference, variable expected

2 errors, 0 warnings



Please, only reach out if you understand what we are talking about and can come with a resolution so that you and me won't waste our time. Also, I'm not going to share the source code, only to the final dev, so no need to ask, the code is well written and there is no other errors.  


Thanks.
