Hi I'm a beginner options trader (former FX trader) and want to make sure I'm picking the right software to get into this field. I'd love to know what folks here are the features in any software that are must haves? I'm particularly curious to know if (and why) it's particularly important to have software that offers options statistics breakdown (e.g. implies/historical vol), volumes of options traded in an underlying as well as option time and sales. Thanks in advance !
