RE: Trailing Stop Loss not Shown and does not work in Tick Level Back Test

Asyc I think should be simulated even in back tests I believe. I mean all the API should be available in backtest otherwise what is the point of the backtest as you will get some incorrect result.

I suspect this might be perhaps due to rounding of the number pips but not sure.

RE: Embedded .Net Compiler Output Not Recognised by VS

VS does not see the build artifacts compiled the cTrader embedded compiler. So even if a reference to the project (indicator) is added it cannot be used in code. Until you also compile the Project (Indicator) using VS also. Then a VS project can reference, see or use the compiled artefacts and the indicator.

If you use other than the embedded compiler (e.g. .net 8) in cTrader this also gives issues.

I am wondering if you can share an example come on how 

GetIndicator(Bars bars, Object[] parameterValues)

is used?

I am trying to create multiple indicators for multiple symbols within the bot. Each indicator will get one timeseries of bars.

Is is not possible to share the code.
