Extensively. Every major parameter is externally configurable without any code changes: Magic Number, Max Spread, lots, risk percent, max lot amount, all six oscillator strategy options, oscillator period, method, applied price, up and down levels, timeframe, grid enable/disable, grid management type, minimum grid distance, distance multiplier, ATR period and multiplier, close-on-indicator mode, take target, stop target, trailing stop values, Friday close settings, and graphic display options. This level of parameter exposure makes Dark Mimas unusually flexible for a free EA and supports meaningful optimization runs in MetaTrader's Strategy Tester.
