PINE LIBRARY
Zaktualizowano 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)
