PINE LIBRARY
تم تحديثه Vantage_LO1_Sizing
**Overview**
Position-sizing library for the LO1 breakout box day-trading strategy. Provides a unified recoup (opposite-add) sizing pipeline and dollar-risk/profit helpers. Extracting these functions into a library avoids Pine Script's function inlining, reducing compiled token count in the main strategy.
**Exported Type: RecoupSizingResult**
Holds the output of the 8-step sizing pipeline:
• Micro-level quantities (raw, DLL-capped, final)
• YM-level quantities (pre/post min-1-YM policy, proxy-capped)
• Risk gate values (projected loss, worst-case drawdown, pass/fail)
• Recoup scenario P&L (net outcome if T1 stops and recoup wins)
**Exported Functions**
`f_calcTradeRiskDollars(entry, stop, qty)` → float
Projected risk in dollars. Converts price distance to ticks via syminfo.mintick, then to dollars via syminfo.pointvalue.
`f_calcTradeProfitDollars(entry, tp, qty)` → float
Projected profit in dollars. Same tick-to-dollar conversion applied to the take-profit distance.
`f_computeRecoupSizing(...)` → RecoupSizingResult
8-step recoup sizing pipeline:
1. Raw micro qty from risk multiplier (CEILING)
2. Daily loss limit cap at micro level
3. Micro-to-YM conversion (FLOOR)
4. Minimum-1-YM policy
5. Proxy capacity cap
6. Micro-equivalent for risk gating
7. Worst-case projection (base stop + opposing flatten + recoup stop)
8. Risk gate pass/fail
Plus scenario P&L: net recoup outcome and T1-win profit.
**Usage**
import Vantage-Stack/Vantage_LO1_Sizing/1 as sz
float risk = sz.f_calcTradeRiskDollars(entry, stop, qty)
sz.RecoupSizingResult r = sz.f_computeRecoupSizing(baseQty, baseEntry, baseStop, recoupEntry, recoupStop,
recoupTP, multiplier, proxyMul, minOneYM, curLoss, maxLoss, maxProxy, t1TP, oppTP, oppFrac, oppRemoval)

Parameters:
baseQtyMicro (int): T1 micro-contract quantity
baseEntry (float): T1 entry price
baseStop (float): T1 stop-loss price
recoupEntry (float): Recoup entry price

f_findBestPartialExit(baseQtyMicro, baseRisk, riskPerMicroRecoup, profitPerMicroRecoup, proxyQtyMul, currentLossDollars, maxDailyLossLimit, maxProxyCap, oppMYMLoss, t1AlreadyClosed, oppositeMultiplier, useRoundUp)
Finds the best partial exit configuration (how many opposing MYM to keep) that passes both risk and profit gates.
Scans k from 0 upward — first passing config wins (prefers full removal when it works).
Parameters:

maxProxyCap (int): Maximum proxy contracts cap (0 = unlimited)
oppMYMLoss (float): Opposing MYM emergency flatten loss per micro
t1AlreadyClosed (bool): Reserved for future use. All current call sites use false (recoup is sized at T1 entry time, not after close).
oppositeMultiplier (float): Target risk multiplier for recoup vs T1
useRoundUp (bool)
Returns: PartialExitResult with best k, adjusted YM qty, and gate results
