Hello.
Few days ago I see a problem with unsubscribing instruments.
I have Tick and Dom subscription and when I send request to unsubscribe this, Tick is not unsubscribed...
Result of request and subscription list on my log:

and request code:

try
{
bool error1 = false;
bool error2 = false;
client.Unsubscribe(contract);
foreach (Subscription subscription in client.Subscriptions)
{
if (subscription.Contract.Symbol == instrument.Symbol && subscription.Type == SubscriptionType.Tick)
error1 = true;
}
client.UnsubscribeDOM(contract);
foreach (Subscription subscription in client.Subscriptions)
{
if (subscription.Contract.Symbol == instrument.Symbol && subscription.Type == SubscriptionType.DOM)
error2 = true;
}
if (!error1 && !error2) Console.WriteLine(Clock.Now + " " + instrument.Symbol + "Tick&Dom Unsubscribed");
else if (!error1 && error2) Console.WriteLine(Clock.Now + " " + instrument.Symbol + "Tick Unsubscribed, DOM unsubscribing FAIL" );
else if (error1 && !error2) Console.WriteLine(Clock.Now + " " + instrument.Symbol + "Dom Unsubscribed, Tick unsubscribing FAIL");
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}

client.Unsubscribe(contract); unsubscribes quotes, not ticks. More accurately, it tries to unsubscribe quotes:
- if you have a position, you will not be able to unsubscribe its quotes;
- there is a reference counter for quote subscriptions: if you have subscribed twice for a contract, you need to unsubscribe also twice.
