  • Mean time between tick changes
  • Median time between tick changes
  • Longest time between trades
  • Longest time between tick changes
  • Mean bid ask spread
  • Median bid ask spread
  • Examples of the round number effect - (both in traded values and traded volumes - i.e. is there an increased probability of the last digit on prices being a 0 compared to other last digits)

The CSV has the following fields / columns:

  • 11 = Date
  • 12 = Time in seconds past midnight
  • 15 = Condition codes

Instructions


This data is over several days and so when no trading occurs there are large time gaps to take into account so as not to skew the figures.

Please also exclude auctions from your analysis. There should be c. 2 auctions a day - morning and afternoon. During this period you will see crossed spreads (i.e. bid price is larger than ask price) along with specific condition codes. Please only include the XT condition code (along with no condition code).

Could you send both the analysis results, along with the code that you have written to complete the analysis as an appendix within 3 working days following the receipt of this invite to one of the following addresses:
