I need a Python script developed that can analyze time-series financial data and detect the presence of any wedge patterns that may be forming. The script should connect to Binance API for historic data as input containing date, open, high, low, close prices. It should then apply technical analysis to identify patterns where the highs/lows are converging and forming either an ascending or descending wedge. The output should be a txt file if a wedge is detected as well as a graph to validate the wedge lines. Complex algorithms may be needed to filter out false positives. Preference will be given to candidates with proven experience in quantitative analysis and pattern recognition using Python. Kindly provide estimates for completing this task along with your relevant qualifications.
