Binance to Binance
Mirror one Binance account onto other Binance accounts.
From ₹6,599/mo · $79 · no card for the trial
A read-only API key on the master, watching its own user data stream.
Every follower is a Binance account of your own, with its own trading key.
Quantity scaled to each follower's own balance.
What you get
The master key is read-only
The account being copied FROM needs no trade permission at all — only the ability to read its own fills. A leak of that key cannot place an order.
Leverage is set per follower, never inherited
The master's leverage is a fact about the master. 20x on somebody else's conviction is not a decision you delegated, so each follower sets its own.
Quantity is scaled, not mirrored
A follower with a tenth of the balance takes a tenth of the size. Copying the raw quantity is how a smaller account gets liquidated on a trade the master survived comfortably.
Three steps, once
Add a read-only key for the master
In Binance API Management, enable Reading only — no trade permission and no withdrawals. The followers use their own trading keys.
Add your followers
Every follower is another Binance account of your own, linked the same way. Each one has its own switch.
Set the sizing rule
Proportional to balance is the default and the only mode that keeps risk equal as the accounts drift apart. Set a maximum per account before you switch it on.
What you will be configuring
Only these 7. There is no channel and no parser on a copier, so none of that appears.
