█ 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

The on-chart table shows everything at a glance:

• ATR — current ATR value with period
  
• ATR Avg — average ATR for volatility comparison
  
• Vol Ratio — current ATR / average ATR (orange when elevated)
  
• Balance — your account balance in USD
  
• Risk % — max loss percentage per trade
  
• Entry — entry price with LONG/SHORT label
  
• Lot — calculated position size
  
• R:R — risk-to-reward ratio
  
• TP — take profit price and expected profit in USD
  
• SL — stop loss price and max loss in USD

█ 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.
