// ─────────────────────────────────────────────
// • This script is FREE and public. I do not charge any fee for it.
// • It is for EDUCATIONAL PURPOSES ONLY and is NOT financial advice.
// • Backtest results can be very different from live trading.
// • Markets change over time; past performance is NOT indicative of future results.
// • You are fully responsible for your own decisions and risk.
//
// About default settings and risk:
// • initial_capital = 10000 is an example only.
// • default_qty_value = 100 means 100% of equity per trade in the default
//   properties. This is AGGRESSIVE and is used only as a stress-test example.
// • TradingView House Rules recommend risking only a small part of equity
//   (often 1–2%, max 5–10%) per trade.
// • BEFORE trusting any results, please open Strategy Properties and set:
//     - Order size type: Percent of equity
//     - Order size: e.g. 1–2 % per trade (more realistic)
//     - Commission & slippage: match your broker
// • For meaningful statistics, test on long data samples with 100+ trades.
//
// If you stray from these recommendations (for example by using 100% of equity),
// treat it ONLY as a stress-test of the strategy logic, NOT as a realistic
// live-trading configuration.
//
// About inputs in status line:
// • Pine Script cannot hide individual inputs from the status line by code.
// • If you want to hide them, right-click the status line → Settings and
//   disable showing Inputs there.

// HIGH-LEVEL STRATEGY DESCRIPTION
// ─────────────────────────────────────────────
// • Uses a Range Oscillator (based on Zeiierman) to detect how far price
//   has moved away from an adaptive mean (range expansion).
// • Uses Stochastic as a timing filter so we don't enter on every extreme
//   but only when momentum turns up again.
// • Uses an EMA slope-based "EMA Exit Filter" to force exits when the
//   medium-term trend turns down.
// • Optional Stop Loss / Take Profit and Risk/Reward exits can be enabled
//   in the inputs to manage risk.
// • Long-only by design.
//
// Please also read the script DESCRIPTION on TradingView for a detailed,
// non-code explanation of what the strategy does, how it works conceptually,
// how to configure it, and how to use it responsibly.
