What Is Mirror Trading? How to Copy Trades Across Broker Accounts

Mirror trading means placing a trade once and having it appear in your other broker accounts automatically. You buy in your main account; the same buy shows up in the others, within seconds, without you touching them.

Trade once. Mirror everywhere.

Who this is for

If you run more than one trading account, you already know the problem.

Maybe you have your own account and manage one for a parent or spouse. Maybe you keep equity at one broker and F&O at another. Maybe you opened a second account for better margins and never closed the first.

Whatever the reason, every trade becomes two or three trades. You take a position in one account, then re-enter it by hand everywhere else — a minute later, at a worse price, and sometimes not at all because a call came in. Exits are where it really hurts, because those are the ones you cannot afford to be late on.

Mirror trading removes that work entirely.

What it does

You pick one account as your master. Everything else you connect becomes a mirror. From then on:

• Every entry and every exit is copied. Buy, sell, open, close — all of it. Not just the trades you remember to repeat.
• It works across brokers. A trade in Zerodha can appear in Dhan, Angel One, Groww or Upstox, in any direction. TradeCraft handles the fact that every broker lists the same contract under a different name.
• It works within one broker too. Several Zerodha logins, for instance, all mirroring from one master.
• You keep your own terminal. Trade in Kite, the Dhan app, whatever you use today. You do not place orders through TradeCraft, and you do not learn a new screen.
• Copies have a price cap. Each copy goes out with a limit just beyond the price you got, so it fills quickly but never at some wild price if the market has jumped. If the price has already run too far, the order waits rather than overpaying.
• Nothing gets copied twice. However many times something is retried behind the scenes, you will not end up with a double position.
• Switching it on never looks backwards. Turn it on at 2pm and your morning trades stay where they are.
• Everything is logged. Each copy is recorded — placed or failed — so you can always see exactly what happened and why.

How to set it up

1. Go to Broker in your dashboard and connect the accounts you want to use. You can add several, including more than one at the same broker.
2. Open Mirror Trading.
3. Choose which account is the master — the one you actually trade in.
4. Turn on the accounts you want it to mirror onto.
5. Switch mirroring on.

That is the whole setup. Place your next trade the way you always do and watch it appear in the others.

What to know before you rely on it

Four honest limits.

Each account needs its own money. Copies go out at the same quantity as the master, so a mirror account needs enough funds and margin for the same position. There is no proportional sizing yet — an account with a quarter of the capital cannot take a quarter-sized position.

Very illiquid contracts may not fill. The price cap that stops you overpaying will occasionally leave an order unfilled on a far out-of-the-money option where the price has moved. Liquid strikes are rarely an issue.

Changing a pending order is not copied. Mirroring happens when a trade actually executes. If you modify or cancel an order that has not filled yet, that change stays in the master account.

It takes a few seconds, not zero. For positions you hold for minutes or longer, this makes no difference. If you scalp in and out inside a few seconds, mirroring is not the right tool.

This is not "follow a stranger"

Copy trading usually means something else: a platform where you follow a trader you have never met and their positions turn up in your account. That arrangement raises real questions in India about who is giving investment advice and whether they are registered to.

Mirror trading is narrower on purpose. It copies your own trades into your own accounts, ones you connected yourself. Nobody else's decisions reach your account, and yours never reach anybody else's.
