SmartFlow Position Sizer Pro

SmartFlow Position Sizer Pro calculates lot size, risk, and reward with precision. Click three points on the chart — Entry, Stop Loss, and Take Profit — and see your entire trade plan instantly. Supports partial take profit, ATR-based volatility adjustment, trailing SL simulation, and multi-currency accounts.

═══════════════════════════════════════

█ HOW IT WORKS

Click three points on the chart:

1st click — Entry Price
2nd click — Stop Loss
3rd click — Take Profit

All three lines are draggable after placement. The indicator works in future (empty) chart areas, allowing you to plan trades before price arrives. Long/Short direction is auto-detected from the Entry vs SL position.

█ FEATURES

Position Sizing

Automatic lot calculation: Balance × Risk% / (SL Distance × Contract Size)
Rounds down to 0.01 to never exceed your risk limit
Supports any instrument: Gold, Forex, Crypto, Indices

Take Profit Modes

Manual — use 3rd click position, drag to adjust
R:R Auto — TP calculated from SL distance × R:R ratio
Partial TP — split exits across TP1/TP2/TP3 with custom allocation percentages and independent R:R targets

ATR Volatility Engine

Current ATR vs average ATR comparison with Vol Ratio display
Automatic lot reduction when volatility exceeds a configurable threshold
Visual background warning during high volatility periods
Customizable ATR period, average period, and threshold multiplier

Trailing SL Simulation

Shows where a trailing stop loss would sit based on ATR × multiplier from current price
Visualized as a separate dotted line — does not interfere with your SL/TP zones

Risk Analysis (Separate Table)

Max Daily Loss — tracks your daily drawdown cap and shows remaining trades before hitting the limit. Essential for prop firm traders (FTMO, MFF, etc.)
Ruin Probability — Balsara-based calculation using your win rate, average R:R, and risk percentage. Color-coded: green (< 10%), red (> 10%)
Losing Streak Simulation — projected account balance after 1, 3, 5, and 10 consecutive losses at your current risk level

Multi-Currency Accounts

Supports USD, EUR, GBP, JPY, AUD, CHF
Live FX conversion via request.security() — all P&L, daily limits, and balance projections displayed in your account currency

Multi-Position Risk

Add up to 2 additional positions manually to calculate combined risk exposure
Combined risk % shown with warning when exceeding daily limit

Trade Journal

Formatted trade summary label on chart: symbol, direction, entry, SL, TP, lot, risk, P&L, R:R

═══════════════════════════════════════

█ LOT CALCULATION

Lot = (Balance × Risk%) / (SL Distance × Contract Size)

For non-USD accounts, balance is converted to USD for calculation, then P&L is converted back to account currency using live FX rates.

When ATR volatility exceeds the threshold, lot size is automatically reduced by the configured percentage (default: 50% reduction).

█ NOTES

All drawing positions use time-based coordinates — works in future chart areas
Designed for MT5/MT4 lot sizing — adjust Contract Size for your broker
Partial TP allocations use R:R-based levels; lot is split proportionally with rounding protection
Alerts available for high volatility entry and normalization
Tip: Disable magnet mode (press A) before adding the indicator to avoid price snapping during clicks
