Bad position sizing is the silent account killer
Most blown accounts are not bad calls. They are good calls in oversized positions. One rushed entry, one forgotten fee, and your risk has drastically increased beyond what you planned.
Here is the same trade on an exchange ticket and in ZRisk, side by side.

You set your risk, the app optimises your entry, and makes sure you carry no excess risk.
From idea to order in seconds
Three steps, every trade. Then the three things underneath them that a spreadsheet or a free calculator cannot do.
Connect
Add your exchange API keys. They are encrypted (AES) on our servers and used only to read your account and place the trades you ask for. Use a key with withdrawals turned off.
Set your risk
Enter your entry, your stop and how much you are willing to lose on the trade.
Trade the size
Get the exact position size, margin and leverage instantly, then place it with confidence.
Know the least you need on the exchange
Every fee is inside the number from the first keystroke, and your risk is worked out together with the liquidation price. That is what gives you the smallest amount this exact trade needs on the exchange, instead of parking your whole balance there to be safe.
- Entry, exit and funding fees priced into the size itself
- Your stop and the liquidation price checked against each other
- Keep the rest of your capital off the exchange
See which exchange is cheapest for this trade
Fees, and more importantly funding, differ by coin and by venue. ZRisk prices the exact same trade on every exchange you use and tells you where it costs the least.
- Your real fees where a key is connected
- Live, per-coin funding for your holding time
- The venue that costs you least on this trade
This trade would cost $0.80 less on Bybit EU.
See what ZRisk keeps in your pocket
A naive risk-over-stop size ignores fees, so a stop-out quietly costs more than you planned. ZRisk sizes the fees in and shows you exactly what that accuracy saves on every trade.
- Fees folded into the size, not bolted on after
- Maker savings when you rest a limit order
- A running tally of what precise sizing saves you
Every trade, automatically, and it adds up fast.
The numbers, not the pitch
What it costs to trade without this, and what people using it actually have to show for it.
What your fees actually cost
Every trade is charged twice, once to get in and once to get out. Nobody adds it up. Put your own numbers in and see the year.
Binance USD-M, VIP 0 taker 0.05% and maker 0.02%. ZRisk prices these into the position size itself and tells you which venue is cheapest for the trade in front of you.

An API key that cannot withdraw cannot lose you money. ZRisk is built around that rule.
No withdrawal access, ever
We only read your account and place the orders you ask for. Use a key with withdrawals disabled, so we can never move your funds.
Encrypted at rest
Your keys are stored with AES-256 encryption on our servers, never in plain text, never shown back to you.
IP-restrict your key
Where the exchange supports it, lock your API key to our server's IP so it is useless anywhere else.
You stay in control
Revoke the key on the exchange at any time and ZRisk instantly loses all access. Nothing is stored you cannot take back.
The free calculator needs no key at all. Connect one only when you want live prices and one-click sizing.
Simple, honest pricing

Frequently asked questions
ZRisk starts with Binance USD-M (USDT margined) Futures. More exchanges are on the way, and the calculator is built to grow beyond a single venue.
Your keys are encrypted (AES-256) at rest on our servers and used only to read your account and place the orders you request. We never have withdrawal access, and we strongly recommend a key with withdrawals disabled and, where supported, IP restrictions.

Yes, from your account in a couple of clicks. Trials require a card and can be cancelled anytime before they end, with no charge.
A free calculator gives you a number. ZRisk sizes fees into that number, shows the least you actually need on the exchange at your leverage, tells you which exchange is cheapest for that specific trade, and places the order for you. It is the difference between a rough estimate and a trade you can act on.
No. Nothing goes to the exchange unless you ask for it. You review the size and confirm each order. The optional auto-replace only re-prices a limit order you already placed, at the levels you set.
Yes. Join our Discord for setups, giveaways, coupon drops and to shape the roadmap with other traders. The link is in the footer and on this page.
Prices stream from the exchange in real time from the top of the order book, which is what a limit order actually prices against. If the feed ever degrades, sizing for live orders is paused rather than acting on a stale number.
No. ZRisk is a calculation tool. Trading futures is risky and you are responsible for your own trades.
