Webtrader

I want to use this Webtrader but it is not available in Deriv.com.

How many was the only Volatility index launched this binary.com since?

On Deriv we have 4 trading platforms; DTrader, DMT5, DBot & SmarTrader. You may try our DTrader platform if your computer has sufficient bandwidth to support the platform as it our improvised platform with the launch of Deriv.

We are not clear on your second question, please rephrase. Thank you.
