The risk management layer
your trading is missing

What is protecting you from another blown account or massive loss?   ProperSizing turns your maximum dollar risk into an exact position size, routes your order, and shows you whether that risk can survive a losing streak.

Most traders don't fail on strategy. They fail because:

Size is a guess

“Two contracts feels right” is not a risk plan. The same stop distance means a different dollar loss on every instrument.

Stops and Targets are an afterthought

Stops and targets placed manually, after entering a trade, under pressure — when the number matters most.

Ruin odds are unknown

Most traders have never calculated the probability that their current risk per trade drains the account or trips a drawdown limit.

The risk layer

Three steps protect your account from unnecessary risk.

  1. 01

    Size to your dollar risk

    Enter max risk, entry, and stop. Get exact size, actual dollar risk, reward:risk, trade direction, and futures micro alternative — live as you type.

  2. 02

    Route with brackets attached

    Submit your sized trade to a connected broker account as an OCO bracket order, so the stop and target exist the moment you're filled.

  3. 03

    Know your risk of ruin

    The Risk Center runs the math on your account balance, max drawdown, win rate, and average win/loss — then helps you find the risk per trade that keeps you in the game.

What's inside

Everything you need. Nothing you don't.

Position Calculator

Tick-accurate entry, stop, and target inputs with live price prefill and floor-rounded contract counts.

Actual dollar risk & R:R

See the real dollar loss if stopped, the potential reward, and the reward:risk ratio before you commit.

Micro Futures alternative

When minis overshoot your risk, get the micro contract count that fits it precisely.

Broker routing

Route your calculated OCO bracket order to your broker.

Risk Center

Risk of ruin for whole-account or drawdown-limit definitions, with a calculated verdict and suggested risk.

Performance tracking

Broker orders with fill status and realized P&L, averages, expectancy, and usage streaks.

Calculator Log

Every calculation you save, in calendar or list view, with full history in the activity workspace.

Default risk & presets

One default risk amount that follows you everywhere, plus saved presets for your regular setups.

Built for the desk or your phone

Fast, distraction-free, and fully responsive — no Calculate button, no clutter.

Who it's for

Traders who wont accept, or simply can't afford, a sizing mistake.

Funded and evaluation traders

Trailing drawdown limits punish oversizing. Size to the limit, not to the feeling.

Discretionary traders

Confidently size different instruments, with different stops, with consistent dollar risk  — every single trade.

Traders rebuilding

Coming back from a blowup or drawdown  means proving to yourself the risk is manageable. This makes it measurable.

Questions, answered.

What does ProperSizing actually do?
It sits between your trade idea and your broker. You enter your max dollar risk, entry, and stop — it returns the exact contract count, the actual dollar risk, reward:risk, and a micro alternative. From there you can route your bracket order to a connected broker and  the outcome gets logged.
Which instruments are supported?
Major CME futures — ES, NQ, RTY, YM, CL, GC — plus their micro contracts, with tick-accurate pricing and live entry price prefill. More in the pipeline.
Which brokers can I route my orders to?
TopStep (combine, express funded, and live funded accounts) is live today with OCO bracket orders.  More brokers are coming soon.
Can I still use ProperSizing if my broker does not currently accept order routing?
Yes — order routing is one feature, not the product.  Without a connected broker you still get the full risk layer: the Position Calculator returns the exact contract count for your dollar risk with tick-accurate entry, stop, and target inputs, live price prefill, floor-rounded sizing, trade direction, actual dollar risk, potential reward, reward:risk, and a micro alternative when minis overshoot. You can save a default risk amount and presets for your regular setups, then place the trade manually in your own platform. Every calculation can be saved to the Calculator Log and reviewed in calendar or list view, with full history in the activity workspace and averages, high-water risk, and weekday streaks on your dashboard. The Risk Center then runs risk of ruin on your account balance, max drawdown, win rate, and average win/loss — for whole-account or drawdown-limit definitions — and gives you a personalized verdict plus the suggested risk per trade that keeps you in the game.
Is my broker API key safe?
Yes. Every broker API key is encrypted with a unique per-user key. And the decryption only happens server-side at the instant an order is routed, and the key is never exposed to the browser. You can disconnect every broker and delete all associated data instantly from your profile.  If your trial expires without a subscription, encrypted broker keys are automatically purged after 14 days.
Can I cancel anytime?
Yes. Start with a 7-day free trial without a credit card, and cancel your subscription at any time from the billing page.
