1. What This Script Is
A **risk and position-sizing calculator** for TradingView, with an **optional mechanical signal add-on**. It does two separate jobs:
1. **Risk Calculator (always on):** tells you how many lots you could safely trade on any chart (Nifty, Bank Nifty, or a stock), given your capital and risk tolerance — the math, not a prediction.
2. **Signal Add-on (optional, toggle on/off):** plots a Buy marker based on one fixed technical rule (EMA crossover, optionally RSI-filtered), then tracks that trade and marks profit-booking levels (T1/T2/T3) and stop-loss on the chart, with alerts.

Release Notes
ns on top of any chart (Nifty, Bank Nifty, or a stock) and answers: "If I enter here, how many lots can I safely trade given my capital and risk tolerance?"
1. Inputs (4 setting groups)
Capital & Risk — your capital, risk % per trade, and Caution/High-Risk thresholds that color-code the dashboard.
Stop-Loss Method — ATR-based (volatility-derived) or Swing High/Low (distance to recent swing point).
Contract Details — lot size (65 for Nifty by default, editable) and direction (Long/Short).
Targets — T1/T2/T3 as multiples of your risk (1R, 2R, 3R), mirroring the T1/T2/T3 in your original screenshot.
2. Calculations
Uses current close as "entry."
Computes stop-loss distance via ta.atr() × multiplier, or highest/lowest price over your lookback.
Derives stop-loss price and the three target prices as R-multiples from entry.
Computes risk amount (capital × risk%), risk per lot (SL distance × lot size), and max safe lots (risk amount ÷ risk per lot) — the same math behind "Safe Lots" in your dashboard tool.
Flags a zone: SAFE / CAUTION / HIGH RISK based on your risk % vs. the thresholds.
3. Visuals
Dashed/dotted lines on the chart for entry, stop-loss, and the three targets.
A dashboard table (top-right corner) showing all the numbers, updated on the latest bar.
What it doesn't do: pull option-chain data (strike, premium, decay) — not accessible
