Tradier
United States. One access token from Tradier's dashboard; the sandbox account has its own.
Where the keys come from
In Tradier's dashboard, under API access, copy the access token. The sandbox, Tradier's paper account, has a token of its own, and the desk needs to know which it is, so switch Sandbox account on for that one.
If your profile has more than one account, put the account number you want in the box; leave it empty and the desk reads the first account on the profile.
On Settings
Pick Tradier · United States, paste the token, set Sandbox if it applies, and click Save and connect. A wrong token, or Sandbox set the wrong way, comes back as "Tradier did not accept this token" with the reason.
What Desk · Home shows
Every position with quantity and cost basis. Tradier's positions read carries no price, so the desk marks every line from Yahoo and values the account live from that. Cash from the balances read.
What it does not show
No futures, no margin bar, no options tape through this read. The options tape on US names is on the Flow screen for every reader.
