The Forex_Pairs_Switcher indicator is a utility for the metaTrader. It is used for fast switching between the FOREX pairs on the current terminal window.

Forex_Pairs_Switcher consists of 3 visual components:

• Vertical Bar – list of the base Currencies.
• Buttons Bar – list of buttons for switching pairs, which correspond to the quote currencies.
• Scroll Buttons - pair scrolling buttons. Located on top.

The selected pair is opened with the template of the current window.

The indicator can be located in any corner of the terminal window. The order of pair switching buttons does not change.

When loading, the terminal checks the availability of the specified pairs at the broker. In addition, it checks availability of the pairs in the Market Watch of the terminal (otherwise, the terminal does not allow to open a chart for the pair). If necessary, the pair is added to the Market Watch.

The indicator uses the Expert Log of the terminal for printing error and warning messages. It is recommended to check the Expert Log after the first start of the indicator.
