Binance simulator app: for practice, or for filming?

The short answer

If you want to practise trading without risking money, you want a demo, testnet or paper-trading mode run by an exchange or a broker, and you’ll find it inside that exchange’s own app or website. The app on this page isn’t that. If you want an exchange on a phone for a video — a skit, a parody, a short film — that is what it’s for, and the rest of this guide explains what it does and doesn’t do.

Two things called a simulator

Search for a Binance simulator, or a Binance demo, and both of those turn up under one word. Most searchers want to place an order, watch it fill and see what the fee takes before real money is involved; a smaller group needs a phone on camera that looks and behaves like a large exchange. The tools don’t overlap, and one request hiding in the same search shouldn’t be served by any tool:

If you want to practise trading

Use a practice mode that works like the real platform. Several large exchanges run a demo or testnet version of their own, and many brokers and charting sites offer paper trading. What’s offered, and where, changes often, so start from the help pages of the exchange you actually mean to use rather than from a list someone else made.

Practice is only as useful as the parts of the real thing it keeps. Look for:

• A live order book, where a limit order can sit unfilled for an hour and a market order in a thin market fills worse than the price you saw.
• The fees you’d actually pay, taken the way the real account takes them.
• The product you mean to trade. Practising spot teaches you nothing about leverage or liquidation, so if futures is the plan, practise futures.
• A way to reset the balance, so you can rehearse the same situation more than once.

Then treat the results with some suspicion. A practice account flatters you: nothing real is at stake, so every decision feels easier than it will with your own money. It’s for learning the controls and the mechanics, not for proving that a plan works.

Get it from the source

Open the exchange’s own app or website and find its practice mode from there. Don’t install a “simulator” from a download link, a file passed around a group chat or a link under a video. A practice mode uses pretend money, so it has no reason to ask you to deposit anything, share a recovery phrase or paste an API key into someone else’s app. Anything that asks for one of those is not a simulator.

Why the app on this page won’t teach you to trade

Pozer makes a Binance-style exchange for filming. It looks close enough to a practice account that the difference isn’t obvious from a screenshot, so here it is plainly:

• The order book is drawn, not collected. Its levels sit one tick apart either side of the last price, and their sizes are worked out from the pair so they hold still while you film. Nobody else is trading on it.
• Every fill lands on the best level of that drawn book — one tick above the last price for a buy, one tick below for a sell — with a flat 0.1% fee. A real fill depends on who is on the other side. These never do.
• Nothing rests. A limit order that doesn’t reach the book comes back Not filled · Did not cross, and Open Orders always reads (0).
• Prices update about once a minute, from a public market feed. That’s enough for a balance to look current, and far too slow for anything to do with timing.
• There are no futures and no leverage. Futures is a tab in the bar with no screen behind it, and the Margin switch on Trade doesn’t move.
• There’s no trade history. A fill prints a receipt, the balances move, and that is the only record of it.

If practising is what you came for, the two sections above are the useful part of this page. Everything below is about filming.

The line you don’t cross

An exchange in a skit is a prop, like a stack of film money. The same screen shown to someone as your account — to back an over-the-counter deal, to reassure an investor, a lender or a landlord, or to get anyone to send you money — is fraud, whichever app drew it. Our acceptable use policy prohibits it, and accounts that do it are closed. It cuts the other way too: a balance on someone else’s phone proves nothing about what they hold, however convincing it looks, and the rest of this page shows how little it takes to make one.

What the filmable version is

Pozer’s exchange template is called Bourse in the editor. It’s an original design laid out the way a large centralised exchange is, which is why we describe it as Binance-style — so you can find the kind of screen you need. It has no connection to Binance and carries no Binance name, logo or artwork. You fill it in, publish it and add it to your phone’s home screen, where it opens fullscreen under your own name and icon. It moves between five screens:

• Home: the balance with Add Funds beside it, a row of shortcut tiles, a promo card, P2P and Convert cards, and the first six coins the exchange lists.
• Markets: the full board, with each coin’s volume, last price and change on the day.
• Trade: a spot order ticket on the left and an order book on the right.
• Convert: a coin-to-coin desk with a single rate and a Preview Order button.
• Assets: the balance again, with Add Funds, Send and Transfer above a list of your coins.

The coins the exchange lists and the coins you own are two separate lists, the way they are on a real venue. The board is the same for every visitor; the holdings are yours. With live prices on — the default — the holdings are valued at the market price, so the same amounts come to a different total from one day to the next.

What responds when you tap it

A real exchange home is mostly furniture, and so is this one. Knowing which is which before you film saves a take.

Works

• Add Funds opens a keypad and ends in a receipt. It sits beside the balance, among the home tiles and on the Assets screen, and it’s the small + beside a balance on Trade and Convert, where it opens on that coin.
• Send, on the Assets screen, opens the same keypad for a withdrawal.
• On Trade: Buy and Sell, the pair chips, the Limit / Market dropdown, the Price and Amount boxes, the stops on the size slider, the Open Orders, Holdings and Bots tabs, the chart fold-out, and the ✕ on the notice strip.
• On Convert: both coin pickers, the swap button between them, the amount box, Max and Preview Order.
• Getting around: Home, Markets, Trade and Assets in the tab bar; the Convert tile and card; the promo card’s Trade button; More beside the markets list; Spot at the top of Convert; and Crypto and Account on the Assets screen.

Furniture

• Futures in the tab bar, the Earn, Recurring and More tiles, the Exchange / Wallet switch, and both search bars.
• The tabs and category chips on the Markets board, the Overview, Earn, Spot, Funding and Futures row on Assets, and the product names across the top of Trade.
• Transfer, the P2P card, the eye beside the Assets balance, the Margin switch, Slippage Tolerance, Instant on Convert, and Copy on the copy-trading card.
• The coins themselves. Tapping a row on the board or in your assets opens nothing.
• The ▾ beside the balance. The unit it shows is chosen in the editor, not on the phone.

Furniture is there to look right in a wide shot. Don’t write a beat around pressing it.

It does the arithmetic an exchange would

What makes it read as an exchange rather than a picture of one is that the numbers are worked out, not typed:

• The balance is each coin’s amount times its price, added up. You never type a total, so the headline can’t disagree with the coins listed under it, and Today’s PNL comes from the same rows and each coin’s move over 24 hours.
• A spot fill charges 0.1%, taken from what arrives: in the coin on a buy, in the stablecoin on a sell. Buy 0.1 BTC and the receipt reads Filled 0.0999 BTC, with 0.000100 BTC as the fee.
• The Convert screen shows no fee because its 0.1% is inside the rate, and it says so: “Zero fees. The rate above already carries the spread.”
• Nothing spends money the account doesn’t have. Order more than your stablecoin covers, or send more of a coin than you hold, and the receipt says Partially filled and shows what actually moved.
• A withdrawal takes a network fee of up to 0.0005 of the coin you send, out of what the amount leaves behind.

The live feed covers BTC, ETH, SOL, BNB, USDT and twenty other widely traded coins, each with its real 24-hour move. A coin it doesn’t cover keeps the price you type, and with live prices off, every figure on the screen is one you chose.

Why film a prop rather than a real account

Mostly because the scene isn’t about anyone’s real money. A skit about the friend who bought the top, a parody of exchange culture, a short film with a trader in it — each needs a phone that behaves like an exchange, not an account. A prop also keeps things off camera that shouldn’t be there: a real account shows your balances and your history, and a stray tap on a real Buy button costs real money. On this one, the numbers do what the script needs, take after take.

Setting one up

1. Open the exchange template in the editor. Name the app — the editor suggests Bourse, Pit, Depth and Vertex — and upload an icon of your own. Skip the icon and it makes a letter tile from the name.
2. Under Holdings, list the coins and amounts the account holds, up to twelve. Under Markets, list what the exchange trades, up to sixteen.
3. Choose Value shown in — BTC, ETH, BNB, SOL, USDT or Fiat — and the Fiat currency: US dollars, euros or rupiah.
4. Tap Create home-screen app. If you aren’t signed in, it asks for your email and sends a six-digit code. Then it gives you a link and a QR code for your phone.
5. Open the link in Safari on iPhone and tap Share, then Add to Home Screen. On Android, open it in Chrome and tap ⋮, then Install app.

Building and installing it is free. On a free account, SIMULATED · POZER.COM sits across the balance, on its bottom edge, and on every receipt, and images exported from the editor carry it too. Pro at US$12.99/mo removes it.

From there: filming a scene on it, staging a portfolio reveal for a skit, and knowing when a still image is all you need.
