I am logging into R|Trader Pro which brings the DOMs up and that works fine. I can trade off the DOMs. Is that what you are talking about? Or the charting software? If you are talking about the charting software, where do I get that?

RTrader Pro, yes.

Can you DM me a screenshot of your connection settings in Sierra?

Sent.

Looks like you're trying to connect to Rithmic 01, not Rithmic Paper Trading.

But there is no Rithmic paper trading in my list on Sierra. That's the only Rithmic feed listed. Where is this other connection? And yes, I feel stupid now. lol.

It's under "Server" in the screenshot you sent.

I can't send you another screenshot for an hour because I'm not an elite member to confirm I have set right, but I have "Rithmic Trading" selected under "Service" as in the other screenshot. I also now have "Paper Trading Server" selected under "Server".

So I'm making progress. When I try to connect, I no longer get an error message, but I do get a change in my candles, then it doesn't connect. So it's like it connects for a split second then doesn't.

R Trader isn't open, running, or logged in to.

I do have 'Trade Simulation Mode On' unchecked.

I double checked user and password.

To repeat, I do get my candles updated from the last time I tried to log in until now, but doesn't stay connected.

I don't use Sierra anymore so I'm doing my best to remember how things are set up, maybe someone else can assist better, but try making sure your symbol is correct. Also check your logs to see what it's saying.

Sierra had reactived my demo account so I could login with it to see if the AMP login might be the problem. I just tried that again and it connected. And my live and sim account are showing under 'Account Balances Window' as @iggod said it should be.

So I went back to my AMP login and again, it tries to connect but then disconnects. There is a small amount of data that comes through as it's trying to connect. Also, under the Account Balance window, my live Rithmic account is showing. On the Sierra demo it showed all 3 of my accounts, AMP, live Rithmic and sim Rithmic. Under AMP just my live Rithmic and no balance.

So it connects under the Sierra demo account, but not under the AMP account, even though my live Rithmic account is now showing in Account Balances. But showing 0 balance.

I really appreciate the help and prompt responses you have been giving.

Yep, makes sense. AMP limits you to AMP accounts. You'd need to use the Sierra Demo or get a paid sierra login direct from them.
Glad it works now!
