Lot Size for Daytraders — Futures Calculator

Description

Instant position size calculator for futures daytraders. NQ, ES, CL, GC & more. Prop firm mode. 100% free, no paywalls. Lot Size for Daytraders is the most powerful, 100% free futures position sizing calculator for Chrome. Built from the ground up for futures traders — not forex traders who occasionally touch NQ. Every contract spec is built in, prop firm rules are pre-loaded, and your results update instantly as you type. No more calculator apps. No more spreadsheets. No more mental math mid-trade. Just open the popup, enter your numbers, and trade with confidence. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ INSTANT POSITION SIZING — 3 STOP LOSS MODES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Enter your risk. Set your stop. Get your contract count — instantly. Stop Loss in Ticks — Enter how many ticks your stop is from entry. The fastest mode for scalpers who think in ticks. If you trade NQ and your stop is 8 ticks, just type 8. Done. Stop Loss in Points — Enter your stop distance in full points. Works perfectly for swing traders and anyone using point-based support and resistance levels. Stop Loss by Price — Enter your exact entry price and your stop price. The calculator figures out the tick distance automatically and gives you your contract count. All three modes update your contract count, dollar risk, tick risk, and point risk in real time. No submit button. No loading. Instant math every time. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 14 FUTURES INSTRUMENTS — EVERY SPEC BUILT IN ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Every instrument ships with the correct tick size and dollar value per tick.

Use Custom Rules and enter your own daily loss limit manually. The DLL progress bar turns orange at 50% usage and red at 75% — giving you a clear visual warning before you're in danger territory. Once you've entered today's P&L and selected an instrument with a stop loss on the Calculator tab, the Prop Firm tab also shows you exactly how many contracts are still safe to trade. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ MICRO CONTRACT SUGGESTIONS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ If your calculated position size comes out to less than 1 full contract, the extension automatically detects this and suggests the equivalent micro contract — showing you exactly how many micros fit within your risk budget. Example: You have a $10,000 account and want to risk 0.5% ($50) on NQ with a 4-tick stop. That gives you 2.5 NQ — which would round down to 2. But if you only have $5,000 and the math says 0.5 NQ, the extension automatically tells you to trade MNQ and shows you the correct number of micro contracts. Never get caught trading 0 contracts when micros are available. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CALCULATION HISTORY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Save any calculation to your history with a single click. Review your last 50 sizing decisions — instrument, number of contracts, dollar risk, stop distance in ticks and points, and timestamp. See exactly what you traded, when, and how much you risked. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FULL CUSTOMIZATION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Default Instrument — Set your go-to contract and it loads pre-selected every time.

History — Choose whether to save calculations or not. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY TRADERS SWITCH FROM OTHER CALCULATORS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Other lot size calculators were built for forex traders, then halfheartedly extended to futures. The result is cluttered menus, paywalled instruments, NaN errors when inputs aren't perfect, and a required TradingView integration that half of all futures traders don't use. Lot Size for Daytraders was built from the ground up, specifically for futures. Here's how it compares: ✓ 100% free — no premium tier, no paywall, no subscription ✓ No TradingView required — works standalone in your browser ✓ Futures-first — NQ, ES, MNQ, MES, CL, GC are front and center ✓ Accurate tick values — built-in and correct, not user-entered ✓ Prop firm DLL tracker — built in, no extra tools needed ✓ No NaN errors — intelligent input handling that always returns a clean result ✓ No account, no login, no email — open and use immediately ✓ Zero ads — clean, distraction-free trading tool ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IS THIS BUILT FOR? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ — NQ and MNQ scalpers and day traders who need instant sizing — ES and MES traders at every account size — Prop firm challenge takers at Apex, TopStep, Tradeify, FTMO, Earn2Trade and beyond — Crude oil (CL) and natural gas (NG) energy traders where a single point is $1,000+ — Gold (GC) and silver (SI) metals futures traders — Bond and dollar index (ZB, DX) macro traders — Traders moving from forex to futures who are still calibrating their risk — Anyone who has ever blown a stop because they sized too big — Prop traders who need to stay within a daily loss limit to protect their funded account — Students and new traders learning proper risk management fundamentals ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY & DATA ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Lot Size for Daytraders collects absolutely zero personal data. There are no analytics, no tracking pixels, no external API calls, and no data transmitted to any server — ever. All calculations happen locally in your browser. Your settings and calculation history are stored only on your own device using Chrome's local storage. The only permission this extension requests is "storage" — and it is used exclusively to remember your settings and save your calculation history locally. Nothing else. No ads. No premium tier. No signup. No email required.
