Hi,

I have one question about API..

How I can generic "Time and Sales" list in API?
I use OECClient.OnPriceChanged and .OnPriceTick events.
This my code:

private OEC.API.OECClient oecClient1 = new OEC.API.OECClient();
private int iTotalVol;
oecClient1.OnPriceTick += new OEC.API.OnPriceChangedEvent(oecClient1_OnPriceTick);
....
void oecClient1_OnPriceTick(OEC.API.Contract Contract, OEC.API.Price Price)
{
if (iTotalVol != Price.TotalVol)
{ listBox1.Items.Add(DateTime.Now.ToLongTimeString() + ":" + DateTime.Now.Millisecond + " Price: " + Price.LastPrice);
iTotalVol = Price.TotalVol;
dPrice = Price.LastPrice;
}
}

But,
if I compare output of this code with chart of OEC, I see difference between this...some events is not come.
Can you help me with this problem?
Thank you in advance and best regards,
Mikhail Iost.

Hello,

you need to subscribe for ticks via OECClient.SubscribeTicks method and process OECClient.OnTicksReceived event.

OnPriceTick is intended to catch all quotes changes without throthling on client-side.

If client application receives more than one quotes while client code is busy, client code will receive one quote with the latest values.
