I don't need to use charts too much, so to increase speed, I'd rather use an app that doesn't rely on charts. If it's fast and has charts, that's great. Ability to set up accounts for exchanges that support it, or ability to create custom accounts for unsupported exchanges ability to script my algorithm What are the software out there I can use for forex currency pairs arbitrage trading?
