Can't get custom events from one cbot to another working

Hi,

I have tried and tried, spent a week googling, AI asking etc but now I'm here.

My plan is to build a Management robot that is a subscriber to multiple Strategy robot's so it can be the master controller of which trades are taken and with what parameters (size, SL, PT, etc). 

I have the Strategy robots creating an object of a custom class that is similar to what cTrader has when using its orders. By this I mean I place all of the details into the object (Symbol, Trade Direction, Label, Size, SL, PT, Comment, custom..). The Management robot might ignore some of this but some information like symbol and label is absolutely necessary.

When the Strategy robot has determined a good entry and created this object I want to invoke an event so the management robot knows there is a strategy that wants to enter, and can then look at the object (reference variable being passed in the event) to see what is what.

But I cannot get the thing to work! I stripped it back to two bare robots with just the eventhandler to try get this working, but I cannot. I reference the Strategy robot in the Management robot either using VS 2022 or locating the dll file within cTrader (once I've built using VS otherwise I can't see any dll file). I'll post below the bare bones of what I'm trying to do.

Just before though…I did use pending orders event notification by actually making a pending order within the strategy robot and subscribing to all pending orders in Management robot but for several reasons I don't like this approach. Also, although I've never done it I know I can get the strategy robot to write to a file and have the Management robot constantly checking this file. But with multiple strategy robots I can imagine this getting messy and being rather inefficient. Please can someone help me with an example of how to use an event to get one cbot listening to multiple others?
