Novo artigo Trabalhando com séries temporais na biblioteca DoEasy (Parte 37): coleção de séries temporais - banco de dados de séries temporais para símbolos e períodos foi publicado:

Este artigo é dedicado à criação de uma coleção de séries temporais com base nos períodos gráficos especificados para todos os símbolos usados no programa. Criaremos uma coleção de séries temporais, os métodos para definir os parâmetros dessas séries e inicialmente as preencheremos com dados históricos.

Estas são todas as modificações do EA de teste.
Vamos compilá-lo e iniciá-lo, após definir nos parâmetros o uso do símbolo atual e do período gráfico atual.
No log serão exibidas as mensagens:

--- Initializing "DoEasy" library ---
Working with the current symbol only: "EURUSD"
Working with the current timeframe only: H4

Timeseries "EURUSD" H4: Requested: 1000, Actual: 1000, Created: 1000, On the server: 5330

Nas configurações, definimos o uso do símbolo atual e a lista de períodos gráficos especificada (na lista são indicados os principais períodos gráficos).
