Your prop accounts. Copied.
Monitored. Protected.

Q: Is copying my own accounts allowed by prop firms?

MirrorFill copies between accounts you own, under your own logins. Most major firms permit personal trade copiers across your own accounts, and a few have restrictions. Always check your firm's rules before connecting.

Q: Do I need a VPS or a machine running all day?

No. The copy engine runs in our cloud and talks to your brokers directly. Close the laptop mid-trade and your stops, targets, and flattens still copy. The browser tab is just a window into it.

Q: Which platforms and firms does it work with?

We connect at the broker layer through Rithmic, Tradovate, and Volumetrica (dxFeed), which covers accounts at Apex, Bulenox, Leeloo, MyFundedFutures, Tradeify, and most funded-account programs. Whatever platform you trade from, if the account runs on a supported provider, it can follow: NinjaTrader 8 works through your Rithmic or Tradovate login, no add-on needed. Named firms are ones whose accounts connect through our supported platforms. That is not an approval by the firm. Always check your firm's current rules.

Q: What happens if my internet drops mid-trade?

Copying runs server-side, so your connection isn't in the loop. If a broker session drops, the engine reconnects automatically, re-reads positions from the broker, and squares up anything it missed once the market is quiet. One drop is never retried: if Rithmic or Volumetrica reports that your login was signed in somewhere else, copying stops safely and you are alerted as soon as it happens, instead of the copier fighting you for the session.

Q: Can each account trade a different size?

Yes, that's the point. Give each follower its own multiplier or a fixed contract count, cap it with a per-account maximum, and micros map to minis automatically.

Q: What does each plan limit?

Never your accounts: every plan copies to as many accounts as you connect. Standard includes two copy groups, each with its own leader. Pro and Private have no group limit.

Q: Do my stops and targets copy?

Your stops and targets stay your own orders on the leader account. While copying, MirrorFill never places, moves or cancels an order on your leader, so it can never remove your stop. When one fills, your position changes, and every follower mirrors that change, so they exit when you exit. Follower entries use a marketable-limit order priced a couple of ticks through your fill, which caps slippage.

Q: Is my broker password safe?

Credentials are encrypted at rest and write-only: the app never displays a stored password, and leaving the field blank on an edit keeps the old one. Support will never ask for your broker password.

Q: Can I use the trade journal before I copy?

Yes. Import a broker CSV (Tradovate exports are auto-detected) and the full journal works on it: metrics, calendar, tags, strategies, and daily notes. Once you copy, fills flow in on their own.

Q: What happens after the 7 days?

Your trial rolls into the plan you picked: $39, $89, or $149 a month, billed through Stripe. Cancel in one click before it renews and you pay nothing.

Simple to run. Boring to rely on.

Per-account sizing

Fixed contracts, multipliers, or risk-matched sizing: a 50K eval and a 300K funded account each get the right size.

Risk guardrails

A daily loss limit and profit target on each account, with flatten and lock or alert only. Max-contract clamps, symbol block-lists and follower protection keep any single account from oversizing. The same tools on every plan.

One-click flatten

A kill switch that closes everything, on every account, everywhere, from any browser, including your phone. It then keeps checking, re-sends any close that did not go through, and tells you loudly if a position is still open.

Symbol mapping

ES to MES, NQ to MNQ, front-month rolls, mapped automatically so micros and minis stay in step.

Your own isolated copier

Every MirrorFill account runs its own copier: its own engine, its own start and stop, its own risk limits and kill switch. It is walled off from every other customer, so nothing another customer does can stop or flatten your copier.

E-mail + Telegram alerts

When a broker connection drops, your login is taken over somewhere else, a risk limit is hit or copying stops, MirrorFill tells you by e-mail and on Telegram, not just inside the app. Linking Telegram takes a couple of taps; there is no bot of your own to build. E-mail on every plan, Telegram on Pro and Private.

TradingView alerts

Point a TradingView alert at your private MirrorFill address and it places the order on your leader account. MirrorFill then copies it to every follower, with the same risk limits and kill switch in front of it, and logs every alert with what it did. Pro and Private.

Every plan starts with 7 days free.

7-day free trial on every plan. Card required at signup. Cancel any time before it converts. You pay for the plan, not per account copied: every plan copies to unlimited accounts.
