hello traders braintrust, i am looking for advice on trading platforms. I do apologies as i don't know where else to post this, but happy to be redirected. I currently use nabtrade and have had drastic issues with its interface not only today but many other days prior. This probably would not be such an issue for me a year ago but I have become more active in my trading, utilising stop losses(shit platform on Nabtrade have to use m.nabtrade), use to be a share investor but making the transition to a share trader and would appreciate any direction on other platforms. Was hoping to get away from the big 4 banks. Thank you for any insight, experience and suggestions.
