WHAT hai break-even stop?

Kisi bhi long trade mein teen prices matter karti hain:

Entry price $E$ — jahan aapne buy kiya.
Initial stop $S_{0}$ — jahan aap apne planned loss ke liye exit karte.
Break-even trigger $T$ — woh price jise touch hone par aap stop ko $E$ par move karte ho.

Aapka initial risk per share hai: $R = E - S_{0}$

Yeh $R$ fundamental unit hai — trade management mein sab kuch "R-multiples" mein measure hota hai.

WHY move karein break-even par?

Lekin cost bhi hai agar bahut jaldi move karo (neeche mistakes dekho). Toh asli skill yeh choose karna hai ki kab move karein.

HOW derive karein trigger — first principles se

Hum trigger ko initial risk ke multiple mein define karte hain. BE multiple ko $k$ maano: $T = E + k R$

$R$ mein kyun express karein? Kyunki $R$ hi ek risk-normalized distance hai jo aapke paas hai. "+2% ke baad BE par move karo" kehna stock ki volatility ko ignore karta hai. "+1R ke baad move karo" kehna automatically stock ke apne noise ke saath scale hota hai.

Expectancy effect derive karna

Maano $p$ = probability ki trade eventually profit target $E + m R$ tak pahunche (ek $m$ -R winner), aur maano $q$ fraction of trades trigger fire hone ke baad lekin target se pehle BE par stop ho jaate hain (scratch = 0).

BE ke bina, jo trade reverse hoti hai woh $S_{0}$ par hit hoti hai aur $- 1 R$ lose karti hai. BE ke saath, wahi reversal ab $0$ lose karti hai. Toh BE loss distribution ko reshape karta hai.

Expectancy per trade (R mein): $E [no BE] = p \cdot m - (1 - p) \cdot 1$

BE ke saath, losers ko "BE par stop" ( $q$ ) aur " $S_{0}$ par stop trigger se pehle" ( $1 - p - q$ ) mein split karo: $E [BE] = p \cdot m + q \cdot 0 - (1 - p - q) \cdot 1$

Subtract karne par: $Δ E = E [BE] - E [no BE] = + q$

The catch (hidden cost): yeh assume kiya ki winners untouched rehte hain. Reality mein, stop upar move karna aapko un trades se shake out kar sakta hai jo jeetnewali thi. Maano $f$ = eventual winners ka fraction jo aap premature BE stop ki wajah se kho dete ho. Tab:

$Δ E = saved losers + q - lost winners f \cdot p \cdot m$

Worked examples

Common mistakes

Recall Feynman: ek 12-saal ke bacche ko samjhao

Socho tumne ₹4 bet lagayi ki tumhara paper plane door tak ud ke jaayega. Jab woh already adha kamra cross kar chuka ho aur clearly accha ud raha ho, tab tum apne dost se kehte ho: "Agar yeh door se pehle land kare, toh na tum mujhe do na main tumhe — barabar." Ab tum apna ₹4 lose nahi kar sakte, lekin agar woh door se nikle tab bhi bade jeett sakte ho. Break-even stop exactly yahi hai: jab trade "kaafi" win kar le, tab deal change karo taaki worst case mein kuch bhi lose na ho.

Recall flashcards

Break-even stop kya hota hai?

Entry price par (plus costs) stop-loss move karna jab price set amount advance kare, taaki max loss ₹0 ho jaaye.

Initial risk per share R ka formula?

R = E - S_{0}

(entry minus initial stop).

Multiple k ke saath BE trigger price ka formula?

T = E + k R

Trigger ko fixed % ki jagah R-multiples mein kyun measure karein?

R stock ki apni volatility ke saath scale karta hai, isliye rule har trade ke noise ke hisaab se adapt hota hai.

BE se expectancy gain kya hoga agar winners kabhi touch na hon?

+ q

R, jahan q = un trades ka fraction jo −1R se scratch mein save hue.

BE use karne ke liye puri net condition kya hai?

BE tabhi use karo jab

q > f \cdot p \cdot m

(bachaaye gaye losers > sacrifice kiye gaye winners).

Long trade mein costs c ke baad true BE stop kahan hona chahiye?

E + c

par, exactly E par nahi.

BE stop ka main psychological benefit kya hai?

Tum winner ko loser mein kabhi nahi badal sakte; trade ke baaki hisse ko calmly hold kar sakte ho.

BE trigger bahut jaldi set karne (chhota k) ka sabse bada danger kya hai?

Normal price noise tumhe acchi trades se stop out kar deta hai (f badhata hai), expectancy hurt hoti hai.

Initial stop-loss placement — $S_{0}$ aur isliye $R$ define karta hai.
Trailing stop methods — BE ke baad ka agla step; profit lock karta hai, sirf breakeven nahi.
Risk-reward ratio and R-multiples — woh $R$ unit jo poore mein use hoti hai.
Expectancy and edge — woh $p \cdot m - (1 - p)$ engine jise humne modify kiya.
Position sizing — yahan define hua R directly kitne shares buy karne mein feed hota hai.
Trade psychology and loss aversion — BE itna compelling kyun lagta hai.
