looks like the code got chopped off..
I like this idea of writing it to a static variable and
using another afl to aggregate all the signals.
For now i have noticed that i am able to run multiple AB
instances connected to the same IQFeed and get away with the problem (at the
expense of some CPU and memory) but i white boarded a bit of a pseudo code that
might help anyone else (or myself when i have to come back to it) who wants to
explore this solution.
In the individual system files, add something like:
In place of the alert-in-system1
add:
If
Ref(Buy,-1)
StaticVarSet("Buy-in-System1",1)
Else
StaticVarSet("Buy-in-System1",0);
In the
new afl file have something like:
BuySignal1Sent
=0; // using these variables as semaphores
SellSignal1Sent
=1;
If(StaticVarGet(Buy-in-System1))
== 1 and BuySignal1Sent == 0)
{
alertif(?..send
the alert to email ? );
BuySignal1Sent =
1;
SellSystem1Sent =
0;
}
