Hi everyone, what is the best/ most cost effective way to trade the XJO/ AUS200 these days ( I prefer to scalp trade the morning and after lunch time sessions )

And what charting software do you people use

Up until now I've used FP Markets and the MT4 platform but noticed when logging in this week after being away for the last 8 weeks the margin requirements are now too high. I think from memory that leverages changed on the 31st of March so that explains that...Some government thing from memory.... 1:100 now 1:30

Any help is greatly appreciated

PS: @5speed used to use Interactive Brokers when he was a regular here, @Patterns trades using Puts and Calls from memory
