Show HN: I've created a trading journal website https://ift.tt/aOzi06T

Show HN: I've created a trading journal website Hi all, Been a while since I've posted and in the time since I have created a trading journal website where you can submit and track your trades with the USP of tracking your outgoings too. There has been a huge rise in the number of retail traders (me included) and a lot of people now have the very real possibility of quitting their day jobs and trading full time. I want to help people do that! It's still in very early stages and I'm releasing new updates daily but would be very grateful to get some other peoples feedback! Thanks in advance and hope you're all having a good day! :D https://ift.tt/iMNDjA2 February 7, 2023 at 04:01AM
