█ WHAT IT DOES
This indicator solves the most common mistake in trading: incorrect position sizing .
You set your account balance and risk %. Then click your Entry and Stop Loss directly on the chart. The indicator instantly calculates:
Lot size — based on your risk tolerance and SL distance
Take Profit — auto-calculated from your R:R ratio
P&L in USD — expected profit and max loss displayed
ATR volatility — current vs average ATR to gauge market conditions
Long/Short auto-detection — determined by Entry vs SL position
═══════════════════════════════════════
█ HOW TO USE
Step 1 — Add the indicator to your chart
Step 2 — Click on the chart to set your Entry Price (1st click)
Step 3 — Click again to set your Stop Loss (2nd click)
That's it. The table and SL/TP zones appear immediately.
Drag the Entry or SL line to adjust — all calculations update in real time
Change R:R ratio in settings to move the TP level
Long or Short is detected automatically — no manual selection needed
Works in future (empty) chart areas — plan trades before price arrives

█ TABLE DISPLAY

Vol Ratio — current ATR / average ATR (orange when elevated)
Balance — your account balance in USD
Risk % — max loss percentage per trade

█ VISUAL ZONES
White line — Entry price
Red zone — SL area (loss zone) with dollar amount on label
Green zone — TP area (profit zone) with dollar amount on label
Zones are drawn between your click positions, not fixed to the latest bar. This means you can place Entry and SL anywhere on the chart — including future empty areas — to plan trades visually before price arrives.

█ LOT CALCULATION FORMULA
Lot = (Balance × Risk%) / (SL Distance × Contract Size)
Example: $10,000 balance, 2% risk, SL distance = $20, contract size = 100
→ Lot = ($10,000 × 0.02) / ($20 × 100) = 0.10 lots
The result is rounded down to the nearest 0.01 to avoid exceeding your risk limit.
