Yeah, i used Angel's Diet Odin, i think ohlc is there but i use candlesticks. It does not hang but if net gets disconnected you have to relogin, it can't reconnect automatically like Nest. Quotes are not fast, there is a 1 or 2 second delay compared to Nest. They had made my quotes to update once every 5 seconds by providing me a diet.angelbolt.com broadcast server, now everytime after i login, i change the server in the registry to fcast.angelbolt.com and have to disconnect and reconnect the broadcast from tools menu for the new fcast to activate, so now there is only a 1 or 2 second delay. i have to do this everytime after i login. i don't know what is their idea by providing slow broadcast to me. Since their server is in bombay and i am in bangalore, it could be related to distance, some bombay users in other thread said they were getting fast quotes in Angel's Odin. i hope this helps.
