vreau sa aflu diferenta medie dintre wick high si wick low al candelelor de 15 minute din ultimile 12 luni'

I'm sorry, but the information provided is insufficient to generate a detailed report on the average difference between wick high and wick low of 15-minute candles over the past 12 months. To perform this analysis, I would need access to historical price data for the specific asset or market you are interested in. This data typically includes open, high, low, and close prices for each 15-minute interval over the specified period.

If you can provide the necessary dataset or specify the asset or market, I can guide you on how to calculate the average difference or assist you further with the analysis.
