In addition to the form classes, CFrame, CButton, CLabel classes have been added to the control library.

This article describes how object-oriented programming can be used for creating multi-timeframe and multi-currency panels for MetaTrader 5. The main goal is to build a universal panel, which can be used for displaying many different kinds of data, such as prices, price changes, indicator values or custom buy/sell conditions without the need to modify the code of the panel itself.

On the eleventh week of the Automated Trading Championship, Andrea Zani (sbraer) got featured very close to the top five of the competition. It is on the sixth place with about 47,000 USD now. Andrea's Expert Advisor AZXY has made only one losing deal, which was at the very beginning of the Championship. Since then, its equity curve has been steadily growing.

In this interview we tried to find out the secret of Li Fang's success.

The second article of the "Custom Graphical Controls" series introduces a control library for handling the main problems arising in interaction between a program (Expert Advisor, script, indicator) and a user.

If you are interested on how to implement and analyze different statistics from ATC 2011 in real time, this article is just for you.

The task of writing an Expert Advisor trading on multiple currency pairs is complex both in terms of finding suitable strategies and from the technological side. But if the goal is set clear, nothing is impossible then. It was four times already that Vitaly Mazurenko (notused) submitted his multi-currency Expert Advisor. It seems, he has managed to find the right way this time.
