EMA Cross Strategy [trugurpala]

//@version=6
// EMA Cross Strategy — ATR SL/TP — github.com/trugurpala/pinescriptv6
// Author: Ugur Pala · mail@ugurpala.com
// Evidence: structural-only; no TradingView compile/chart record exists.
// Uses chart-timeframe values and default strategy recalculation/order-processing settings.
// With default semantics, signals are calculated at bar close; new orders are normally first eligible on the next tick.
// TradingView must verify actual chart behavior.
// Commission is a fixed 0.1% example assumption; slippage is not configured.
// Stops/targets use the signal bar's close and ATR, not from a confirmed actual fill price.
// No alert workflow is configured in this example.
