What Symbols are available

I recently changed to a different broker and found the available currency airs (or symbols) were different.

Is there any easy way to :-

1. Access all Symbols from an EA

2. Check the availability of a Symbol from an EA

2) (old way) MarketWatch => Right-MouseClick => Show all (and https://docs.mql4.com/marketinformation/symbolstotal ) (b600+ might have a function to do this)

1) if Symbol is in the MarketWatch (2) you can get the high like iHigh("Symbol", TimeFrame, bar).

Many thanks
