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, one mistyped stop, and your risk is suddenly five times what you planned. CalTrade makes that mistake impossible.

Everything a futures trader needs to size up

Purpose built for fast, repeatable risk management, not a generic spreadsheet.

Live prices

Prices stream straight from the exchange, so your size always reflects the real market.

Fees included

Maker, taker and funding fees are part of every number you see, down to the cent.

Risk based sizing

Set a dollar or percent risk and get the exact size that respects it, every time.

Stop loss your way

Move your stop or recalculate the size, with a deviation buffer for slippage.

Limit order helper

Your limit orders replace automatically at the levels you set, so you never chase a fill.

Keyboard first

Tab through every field and size a trade without ever reaching for the mouse.

Risk control

The same risk on every single trade

Decide how much you are willing to lose, and the calculator does the rest. No more oversized positions in a moment of conviction, no more napkin math.

  • Dollar or percent risk
  • Deviation buffer for slippage

True cost

Know what trading actually costs you

Fees quietly eat returns. CalTrade folds maker, taker and funding fees into every figure, and summarises what you have paid across your history.

Stops and limits, handled

Two stop loss modes let you move the stop or recalculate the size. Limit orders replace themselves at your levels so your plan survives a fast market.
