Grebenka: MT5 chart marking assistant with manual ZigZag and hotkeys for clarity

This Grebenka review provides a practical 2026 performance analysis of the indicator as used on MT5 charts. Developed by Aleh Daikou, Grebenka acts as an assistant for chart markup, enabling traders to draw ZigZag lines manually with mouse clicks while offering horizontal alignment and quick hotkey controls. The first notable element in this review is the focus on human-in-the-loop charting: Grebenka does not automatically place orders, instead it reduces friction when defining pivots and trendlines, which can improve setup consistency and decision speed. What makes Grebenka unique is the blend of manual control and small automation conveniences. The algorithm behind the indicator is lightweight: it records clicked points, draws continuous ZigZag segments, and optionally snaps the active trendline to a horizontal price. Grebenka handles rapid redraws and color swaps without redrawing entire templates, which is useful under volatile market conditions. Best performance is observed on liquid FX and commodity pairs where pivot clarity matters. Risk management responsibility remains with the trader; Grebenka supports disciplined planning by making trendline placement reproducible. Expected characteristics include faster chart preparation, fewer misaligned trendlines, and clearer multi-timeframe context. In practice Grebenka speeds review and planning workflows and reduces manual chart clutter, while requiring a trader to apply their own entry rules and money management.
