I am experiencing ongoing (over 2 months) Rithmic data latency issues. I'm currently doing an evaluation with Apex trader funding. At the open of RTH every day, the latency sometimes gets over 200,000ms. I've been in contact with Rithmic and Apex about the issues but there doesn't seem to be any solution thus far. Trading platform is Quantower. Here's what I've done from my end:
New CPU (i7 -7700k). The switch from my old CPU made no difference at all.
New SSD hard drive
Sync time zone regularly.
I have 100mbps internet connection with a 10ms ping.
Not running any superfluous programs. Only 2 charts and 1 indicator.
This has been driving me crazy lately. Would love to know if anyone can suggest a solution or has dealt with a similar issue.
Can you help answer these questions from other members on NexusFi?
Thanks for your reply. I'm in Korea and I've tried Chicago, Seoul, Tokyo, Singapore.
When it's working (outside of RTH and at less volatile times), Seoul seems to have the best ping.
At the current moment, I can't even log in to RTrader pro successfully on Chicago, or Seoul.
I have frequent connection/delay issues with them as well, including orders that are sent but not processed. Frustrating and dangerous. You're not alone.
200,000 ms delay is often a signal of server-side TCP buffering because the client is not consuming the data fast enough.
Check with Rithmic if you're receiving data from them via TCP transport. If so, consider ways to optimize this, e.g. significantly increase the size of your TCP receive buffer, or ensure no slow application logic is creating backpressure or blocking your dispatcher from reading off the TCP socket.
>>For example, for a connection that has a latency of 10 ms, the total achievable throughput is only 51 Mbps. This value is reasonable for a large corporate network infrastructure. However, by using autotuning to adjust the receive window, the connection can achieve the full line rate of a 1-Gbps connection.<<
>>To review the current settings, open a Command Prompt window and run the following command:
cmd
Firstly Ninja Trader is not fit for purpose, and neither is the rithmic data feed. I have had multiple order rejections and slow downs, failed orders, and positions that can not be exited. I passed this on to Apex and rithmic with no solution or answers.
I have videos of orders being rejected and positions stuck until exited for account stop loss being breeched.This has had on a few occasions and no solutions have been found. APEX seem to ignore the issue only once rectifying the problem.
Another issue is trading the open is practically impossible. Your orders will freeze and data feed will getting to a halt. This seems to Happen at the time the order is filled. Abd I assume its a messaging issue.
Trying a new prop trading service with data feed and brokerage through Rithmic. I like the idea of placing trades through same service as data feed and platform, but it's kind of clunky. Just crashed when I tried to look back for a month's worth of data. Thankfully I didn't have a trade on. Seems hard to believe that very many people trade on this platform. Anybody here trade with Rithmic?
