Cannot subscribe to events problem

[Loggy48]

I have a problem which must be in my strategy but I cannot see it.

I am trying to subscribe to events so that I can trace stoploss and other things.

I have a strategy that has been doing this for a long time now without difficulty although it needs some improvement to monitor the CustomID/QTXT so that I avoid interference with any other strategy or manual intervention.

But for some reason I cannot trace the events.

Here is a totally stripped down strategy that doesn't actually trade but should report the events via AsyncOperationFinished:

Code: Select all

function Init()
   strategy:name("Skeleton")
   strategy:description("No flesh")
end
local TRADE_EVENT = 1001
local ORDER_EVENT = 1002
local OFFER_EVENT = 1003
local host = core.host
local period = 0
function Prepare(onlyName)
   instance:name(profile:id() .. "(" .. instance.bid:instrument() .. ")")
   if onlyName then return end
   host:execute("subscribeTradeEvents", OFFER_EVENT , "offers")
   host:execute("subscribeTradeEvents", ORDER_EVENT , "orders")
   host:execute("subscribeTradeEvents", TRADE_EVENT , "trades")   
end
function Update()
   period = period + 1
   xprint("Update entered "..period)
end
function AsyncOperationFinished(cookie, success, message)
   xprint("AOF entered with cookie "..cookie.." success "..success.." message "..message)
end
function xprint(txt)
   host:trace(txt)
end

As I said, very simple. I can import this and run it.

There are no error messages in the event logger other than the message from Update - ie I do not see a message "AOF entered..... " at all which should occcur whenever an offer, order or trade is made on the instrument.

This occurs on two PCs so I don't think it is a PC setting at all and previously it was working perfectly well.

(er, yes, it requires a tostring() round the success boolean ).

This skeleton strategy (and its more complex relation) appears to work OK both in simulation mode and in backtesting but not on my Demo account on which I was testing it, although I have another strategy that worked OK on the Demo account.

Very puzzling but at least with simulation I can trace what is happening.
