Sierra Chart

Install on Sierra Chart

quantedOptions Profile on your Sierra Chart charts. About ten minutes.

Before you start

Sierra Chart 64-bit, build 2910 or newer. Know where your Data Files Folder is: open Global Settings › General Settings › Paths and read the Data Files Folder path — usually C:\SierraChart\Data.

Install

Sign in at your Orderflow Plugin page and download quantedoptions_profile_sierra.zip. The page lists the platforms on your plan and shows your API key.
Unzip it.
Inside: quantedOptions_Profile_64.dll and a licence file. Only the DLL is installed.
Close Sierra Chart.
Copy quantedOptions_Profile_64.dll into your Data Files Folder.
For example C:\SierraChart\Data.
Start Sierra Chart and open a chart for ES, MES, NQ, MNQ, RTY, M2K, YM, MYM, GC or MGC.
Open Analysis › Studies › Add Custom Study.
Expand quantedOptions Profile in the list, select the study named quantedOptions Profile, click Add, then Settings.
Fill in the connection inputs (below), leave HTTP engine on Built-in (no flicker), click OK.
Wait a few seconds.
Until data arrives the chart shows a small label reading quantedOptions Profile - connecting.

Connection settings

Same on every platform; only the labels differ a little.

Setting	Enter
`API base URL ('mock' = demo data, no key needed)`	`https://www.quantedoptions.com/api`
`API key (qo_live_...; empty = reuse %APPDATA%\quantedOptions\plugin.json)`	your `qo_live_…` key
`Options underlying (AUTO = from the chart symbol)`	`AUTO`
`Price conversion to this chart (AUTO = by instrument)`	`AUTO`
`Book (today's / nearest expiry = 0DTE …; All expiries = …)`	`Today's / nearest expiry`

The ladder and panel appear within a few seconds. The key is remembered on this machine.

Every other setting is one line each on Settings explained.

How to tell it works

A ladder of bars on the right of the chart, one per strike, and a small panel in the bottom-left corner. The panel's first line names the chart and the source — ES · from SPX 0DTE 08-19 — then the prices: SPX 6480.25 → ES 6512.00.

The dot in the panel header: green = fresh, amber = a few minutes old, red = stale. Outside market hours the last data is held and the dot stays green.

Update to a new version

Open Analysis › Build Custom Studies DLL and choose Build › Release All DLLs and Deny Load. Replace the DLL in the Data Files Folder, then choose Allow Load DLLs in the same window. Or simply close Sierra Chart, replace the file, and start it again.

If it doesn't work

What you see	What to do
The label reads `error: HTTP 403 (check API key)` or `HTTP 401`	Fix the key or update the DLL.
The label reads `error:` with another message	Check that the URL has `www`.
The study is not in the Add Custom Study list	The DLL is in the wrong folder. Check the Paths setting again.
Where the log is	Window › Message Log — entries from the study start with `qO Profile`.
The panel or label reports HTTP 401 or 403	Check the key: copy it again from your plugin page, no spaces at either end. A 403 also happens with an out-of-date plugin file — download the current one.
Nothing draws and there is no error	Check the URL. It must be exactly `https://www.quantedoptions.com/api`. Without `www` the request is redirected and the plugin does not follow redirects.
Bars draw at the wrong prices	The chart has no live last price yet (a fresh chart with no ticks, or a symbol the plugin does not recognise). Wait for a tick, or set the underlying by hand.
The panel says rate limited	You have more charts open than the key allows across all machines. Close a few, or wait a minute.

Still stuck: send a screenshot and the log lines starting qO Profile.
