FingerprintCaptureScript: Export OHLC fingerprint CSVs for precise MT5 pattern analysis

FingerprintCaptureScript review 2026 performance analysis focuses on data fidelity and workflow efficiency for MT5 users. FingerprintCaptureScript stands out because it converts visually marked chart ranges into structured semicolon-separated CSVs, preserving open, high, low and close values for each candle between two vertical line objects. The author, Filip Dockal, designed the script to read exactly two VLINE objects on the active chart and treat them as start and end markers, then export the selected candles into Terminal → Common → Files with consistent formatting and timestamping. The algorithm itself is straightforward: it enumerates bars within the marker range, captures OHLC and time, and writes rows to disk; there is no decision logic or order management, which reduces complexity and eliminates market execution risk. FingerprintCaptureScript performs best on historical data where patterns are clearly visible and when users need repeatable datasets for machine learning or manual inspection. Risk management in the context of this utility is about data integrity and workflow control rather than capital preservation, since the script does not trade. Expected performance characteristics include sub-second export times on ranges up to several thousand candles, consistent file formatting, and negligible resource overhead, enabling frequent captures during exploratory analysis without disrupting other MT5 operations.
