I used the code from the URL at [1] and other places on OpenECry but I can not get historical market data to show up. The event for oecapi_OnBarsReceived is called but the bars object is empty.

I've tried the code below with DateTime.UtcNow for both values , and it still doesnt work.

oecapi.RequestBars(contract,
OEC.API.Duration.Date( DateTime.Now.AddDays(-6), DateTime.Now),
OEC.API.BarDescription.HoursMinutes(5));

Victor,

I can get historical bars if I change the interval to 15 instead of 5. Any idea why this doesnt work for 5 min bars ?

static void oecapi_OnLoginComplete()
{
OEC.API.Contract someES = oecapi.BaseContracts["ES"].Contracts.First;
if (someES != null)
DisplayContract(someES);
OEC.API.Contract ESU2 = oecapi.Contracts["ESH4"];
if (ESU2 != null)
DisplayContract(ESU2);

EsSymbolLookupRequest = oecapi.SymbolLookup("ESH4");
}

Can you reproduce it in OEC Sample or OEC Trader?

I noticed that this user is using:

(DateTime.Now.AddDays(-6), DateTime.Now)

Should that not be DateTime.UtcNow.AddDays(-6), DateTime.UtcNow)?

Source is the same as user indicated.

I actually used DateTime.UtcNow.AddDays(-6), DateTime.UtcNow) when I was testing and it only worked sometimes. I've been using that for the last 2 weeks and I only get bars if I switch the interval and restart the program to request new bars.

I'm not sure why its this buggy. I really love the API but I dont think its my code when its working sometimes but not others.
