Before You Start

A Signal Trade App account. New accounts start with a 5-day trial (card required).
Two or more Propr accounts: one to trade (the leader) and one or more to copy to (followers).
At launch, Propr Beta accounts can be connected. A Live option appears in the form once Live Propr accounts are switched on.

Step 1: Create a Propr API Key

Log in to Propr.
Open Settings → Developer and create an API key. It starts with pk_.
Copy it. Do this once for each Propr account you will connect.

Step 2: Add the Connection

In Signal Trade App, open Connections and click Add.
Choose Propr and the environment (Beta or Live).
Paste the API key and click Add Connection. We check the key with Propr before saving it, store it encrypted, and only use it for your trades.
Repeat for every Propr account.

Step 3: Set Leverage and Margin in Propr

Leverage: set each follower at least as high as the leader in every market you trade. Copies use the leader’s size × your ratio; with lower leverage a large copy can need more margin than the follower has, and Propr refuses it. The notice says which leverage would fit.
Margin mode: cross is recommended. Isolated margin can liquidate a copied position before your drawdown limit. Stock and commodity markets are isolated only.
Signal Trade App never changes your leverage or margin mode.

Step 4: Create a Copy Group

Open the Cockpit and create a group.
Pick the Propr account you trade as the leader.
Add the other Propr accounts as followers. Only Propr accounts are listed: a group holds accounts from one venue.
Set each follower’s copy ratio: ×1 for the same size, ×2 for double, and so on.
Leave Protect on. When the leader goes flat in a market, Protect closes the follower there too.
Turn following on.

Step 5: Test With a Small Trade

Buy a small amount on the leader, for example 0.001 BTC (about $10 or more, above the minimum order on live accounts). Within about a second every follower should show the same position × its ratio in the Cockpit. Close the leader and check that every follower goes flat.

How Copies Behave

Fills are copied as market orders. A resting limit order is copied when it fills.
Sizes are fractional and rounded to each market’s size step.
Copies below the minimum order (about $10 on live accounts) are skipped with a notice. Closes always copy.
Reversals copy as a close then a new entry, one after the other.
Followers do not hold their own take profit or stop loss; Protect closes them when the leader exits.

Frequently Asked Questions

Where do I find my Propr API key?

In Propr under Settings → Developer. Create one key per account.

Why was a copy refused for margin?

The follower did not have enough margin for the copied size, usually because its leverage is lower than the leader’s. Raise the follower’s leverage in Propr or lower its ratio.

Why was a small trade not copied?

The leader’s fill × your ratio was below Propr’s minimum order (about $10 on live accounts). You get a notice when this happens. Closing orders are never skipped.

Can I copy from Propr to a Tradovate or Rithmic account?

No. Copy groups hold accounts from one venue. Propr accounts copy to Propr accounts.

Can I trade Propr from the Signal Trade App chart?

Yes. A connected Propr account unlocks the chart with Propr markets and fractional order sizes. Orders on the leader from the chart are copied like any other fill.
