Mac menu-bar app · ₹499 one-time
⌥Space from any app. Type an entry and a stop — every risk step is sized, charges and break-even folded in.
One-time ₹499 — or included free with a TickerMantis subscription · Apple silicon · macOS 13 Ventura or later. The panel above is the real thing — free to use in your browser as long as you like.
What it does
Sizing
Every risk step you keep — 0.5%, 1%, 1.5%, 2% by default — sized side by side, so you choose the column instead of recalculating. Quantity always rounds down, so a position never risks more than its budget: whole shares in INR, and to a ten-thousandth for a US long, where brokers sell fractions.
Charges
NSE: brokerage, STT, exchange transaction, SEBI, GST and stamp duty, for intraday or delivery. US: commission, the SEC's Section 31 fee and FINRA's activity fee, both on the sell leg. Whichever applies is folded into break-even and every net figure.
Targets
1R through 4R with the price and what each actually nets after costs — plus your own target as its own precise row, labelled with its R multiple.
Capital
Three presets plus a slot you type into, kept separately per market — a dollar account is not a rupee one converted, and there is no exchange rate anywhere. Digits group as that market does (1,00,00,000 against 10,000,000). A column dims when the position would exceed capital.
Menu bar
A SwiftUI panel hanging off a status item. ⌥Space raises it over whatever you are in; press again and focus goes straight back.
Private
No account, no sign-in, no network calls, no analytics. Settings and the last five setups live on your own device.
Hands stay on the keyboard
The panel shortcut toggles — the same keystroke raises and dismisses it, and dismissing hands focus back to the app underneath. Only the panel shortcut is rebindable, under Settings → Keyboard.
On this page the 1–4 keys copy a column’s quantity, and tab and return move between the fields as listed; esc leaves the field you are in. ⌥Space and the ⌘ shortcuts are Mac-app only.
One-time purchase
Position Calculator is an arithmetic tool for discretionary use. Indian charge rates are Zerodha-style defaults with statutory components at the rates effective Mar 2026; US rates are the published zero commission, the SEC's Section 31 fee and FINRA's activity fee as of Aug 2026. Both regulatory schedules are revised often — verify against your broker's contract note before acting on a figure. TickerMantis is not registered with SEBI as a Research Analyst or Investment Adviser. Nothing here is investment advice or a recommendation on any security, and the app does not execute trades, assure returns or guarantee results. Securities-market investment carries risk, including loss of capital. The app is sold as a one-time purchase; taxes may apply at checkout and refunds follow the TickerMantis payment terms.
