// 3. SIGNAL LOGIC (ENTRY CONDITIONS)
//──────────────────────────────────────────────────────────────────────────────
//
// Idea:
// - LONG bias: RSI emerges from oversold AND MACD crosses above signal below zero
// - SHORT bias: RSI falls from overbought AND MACD crosses below signal above zero
//
// Combines momentum (RSI) with trend confirmation (MACD).
//──────────────────────────────────────────────────────────────────────────────

// RSI events
rsiBullCross = ta.crossover(rsiValue, rsiOversold) // RSI crosses UP out of oversold
rsiBearCross = ta.crossunder(rsiValue, rsiOverbought) // RSI crosses DOWN from overbought

// MACD crossover with trend filter
macdBullCross = ta.crossover(macdValue, macdSignal) and macdValue < 0 // Bullish cross below zero-line
macdBearCross = ta.crossunder(macdValue, macdSignal) and macdValue > 0 // Bearish cross above zero-line

// Raw (ungated) entry signals
rawLongSignal = rsiBullCross and macdBullCross
rawShortSignal = rsiBearCross and macdBearCross

// 4. STATE MANAGEMENT (SIMULATED POSITION TRACKING)
//──────────────────────────────────────────────────────────────────────────────
//
// position: 1 = long
// -1 = short
// 0 = flat
//
// We track entry price and SL/TP levels as if this were a strategy.
// This is still an indicator – it just computes and plots the logic.

//──────────────────────────────────────────────────────────────────────────────
//
// Only take a new trade when flat.

// 9. QUICK USAGE NOTES
//──────────────────────────────────────────────────────────────────────────────
//
// - Indicador, não estratégia: ele simula posição, SL/TP e sinais de saída.
// - Para backtest/auto, basta portar a mesma lógica para um script `strategy()`
// usando `strategy.entry` e `strategy.exit`.
// - Em day trade, teste ATR vs Percent e ajuste os multiplicadores ao ativo.
