New article Prices in DoEasy library (part 60): Series list of symbol tick data has been published:

In this article, I will create the list for storing tick data of a single symbol and check its creation and retrieval of required data in an EA. Tick data lists that are individual for each used symbol will further constitute a collection of tick data.

Compile the EA and launch it on any symbol chart having preliminary defined in the settings to use the current symbol and the current timeframe. When initializing the EA, data on EA parameters, on created timeseries, as well as (a bit later) on created tick series are to be displayed. The data on two found ticks with the highest Ask and lowest Bid for the day are to be displayed below:
