Amend existing code to save two additional pieces of data

Simple amendment to existing code that records tick data to a CSV file. Currently the code is added to a single chart in Metatrader as an EA and the user specifies the pairs for which tick data should be recorded. Data is written to a CSV file for each pair with the date and time plus the tick price. The project is to amend the code to record the bid and ask price in addition to the date/time/tick value at the time of each tick.
