Position size decides whether a losing streak is survivable. Set your account and risk % once — that is 1R.

Stocks: enter entry, stop and target to get the share count that risks at most 1R (fees included), capped by your max position %, plus 1R/2R/3R price levels.
Crypto: entry, stop, leverage and the exchange’s quantity step give you coin quantity, notional, margin used, and a warning if your stop sits beyond the approximate liquidation price.
Watchlist: size up to 20 ideas at once and flag reward:risk under 1.5R. Long/short detected automatically.

Excel + Google Sheets, Arabic RTL + English, no macros, formulas tested.

حاسبة عربية/إنجليزية لحجم المركز: عدد الأسهم أو كمية العملة التي لا تتجاوز 1R، مع العمولة وسقف المركز، وفحص الرافعة وسعر التصفية للكريبتو، وحساب ٢٠ فكرة دفعة واحدة.
