How to Copy Trade Multiple Propr Accounts at Once

Category: Prop Firms | Date: 2026-11-02

Why Traders Run Several Propr Accounts

Funded traders often run more than one challenge: to spread the cost of a failed evaluation, to scale up after a pass, or to trade different account sizes. Trading each one by hand means repeating every entry and exit, and the accounts drift apart. A copier keeps them in step.

The Setup

Connect each Propr account. In Propr, create an API key per account (Settings → Developer). In Signal Trade App, go to Connections → Add → Propr and paste it. The key is checked with Propr before it is saved.
Pick a leader. The account you will actually trade.
Create a copy group. In the Cockpit, create a group with that leader and add the other Propr accounts as followers.
Set each follower’s ratio. ×1 copies the same size; ×2 doubles it for an account twice the size.
Check leverage on each follower. At least as high as the leader’s. Cross margin is recommended.
Test. Place a small trade on the leader and watch every follower fill in the Cockpit.

Sizing Followers of Different Sizes

Account	Balance	Ratio	Leader buys 0.01 BTC → follower buys
Leader	$10,000	—	0.01 BTC
Follower A	$10,000	×1	0.01 BTC
Follower B	$25,000	×2	0.02 BTC
Follower C	$50,000	×5	0.05 BTC

Size the leader for your smallest account and give larger followers a higher ratio. Every copy is the leader’s order size × the ratio; followers are never sized from what they already hold, so they stay in proportion through adds and partial exits.

Trading the Leader

Trade the leader wherever you like: the Propr web app, or the Signal Trade App chart, which shows Propr markets and takes fractional sizes. Fills are what get copied; a resting limit order is copied once it fills.

Keeping Accounts Safe

Keep Protect on: when the leader goes flat in a market, each follower is closed there too.
Use Flatten in the Cockpit to close every account in the group at once.
Watch each account’s drawdown and open P&L in the Cockpit.
A copy group is Propr-only. Futures accounts on Tradovate or Rithmic go in their own groups.

Read your Propr account rules on copying between your own accounts before you start.

Frequently Asked Questions

How many Propr accounts can I copy to?

There is no account limit on the plan. Add as many Propr followers to a group as you need.

Do I need a separate API key for each Propr account?

Yes. Create one key per Propr account and add each as its own connection.

Can followers have different sizes?

Yes. Each follower has its own copy ratio, so a larger account can copy at ×2 or ×5.

Can I trade the leader from the Propr web app?

Yes. Any fill on the leader is copied, wherever the order was placed.
