API Support » DEMO server is slow Feb 21, 2023 @ 08:24 AM (Total replies: 3)

Any idea? The LIVE also seems to have slowed down dramatically...

By DEMO, I meant the SIM server

It takes much much longer to request for tick data from the DEMO server, any issues?

FIX Support » FAST Logon SendingTime encoding Sep 25, 2022 @ 11:24 PM (Total replies: 2)

I enabled packet sniffing and sent this foxscript

LOADTICKS ES 202212 FROM [20220921-22:00:00] TO [20220922-21:00:00]
: MarketDataRequest -> {59, V, ES202212_2_2, 0, 1, 1, 2, 20220921220000, 20220922210000, [ [MDEntries -> {0, }] [MDEntries -> {1, }] [MDEntries -> {2, }] ], [ [Instruments -> {ES, 202212, , , FXXXXS, }] ], }

However, these are the actual values sent down the wire:

20220921220001 (instead of 20220921220000)
20220922210001 (instead of 20220922220000)

202213 (instead of 202212)

This is the actual byte sequence
F8 BB 45 53 32 30 32 32 31 32 5F 32 5F B2 80 81 81 83 04 4C 40 66 4E 17 A1 04 4C 40 67 0A 4D D1 83 C0 B0 C0 B1 80 81 45 D3 0C 2B E5 80 80 46 58 58 58 58 D3

Since 202212 is even number, hex must also be even, however it is 0C 2B E5, I was expecting it to be 0C 2B E4
Likewise for the dates, ending with A1 and D1 respectively...

Anyone can explain what's going on???

FIX Support » FAST Logon SendingTime encoding Sep 23, 2022 @ 10:25 PM (Total replies: 2)

The template for FAST Logon has a field 'uInt64 name="SendingTime" id="52"'

Can give an example of how I should be encoding "2022-09-24T02:05:21-0000"?

Thank you.

Can help explain how we should craft "7d 82", what does it mean? Or is it just a fixed value?

thanks!

I saw this:

Account=[OEC Account]
Username=[OEC UUID]
SenderCompID=[OEC Username]
Password=[OEC Password]

1. Is the OEC UUID for FIX/FAST same as the UUID for the .NET API?
2. How do I get a UUID for the STAGE or DEMO server?

Hi Jason,

Thanks, I need to test it, but I think it will work once I switch to 4.0.3.44.

However,

1. Is 4.0.3.12 still supported? I had no news on it, so this really came as a surprise
2. Assuming it is, then this issue should be fixed at the LIVE server, yes?
3. If it is not, where do I sign up for updates?

Thanks.

Hi,

My Gf.Api.Dll version 4.0.3.12 is throwing an exception when logging into LIVE.
The same binary does not throw any exception when logging into DEMO.
Object reference not set to an instance of an object
The issue started today 21st May 2021. Please advise.
