Platform "kill button" for the day

This would be another kind of risk rules/management feature. It would be a button that (if you’re flat) logs you out and and prevents you from logging back in until market open the next day (or perhaps a time of your choice). This would be a method to prevent yourself from over-trading, so if you’re happy with your gains or want to prevent further loss for the day you can hit the kill button so you aren’t tempted to look for opportunities to get back into a trade.
