Only the option charts are slow to load, stocks load quick. I run a chart , Market depth , book trader , T& S , news feed and and activity scanner and use the classic TWS . My set up is somewhat sparse and I only monitor about 6 stocks or options a day in TWS , Most of my monitoring is with Street Smart Edge . I also run Schwab Street Smart Edge at the same time. Where I also get a lag is when I want to modify a trade. I have been using TWS for over 20 years . I have a 1 gigabit Internet connection. It takes about 30 seconds for TWS to fully load. FYI I have a Samsung Pro 970 NVME drive .
A full windows install is a big deal and this might not even be the issue , you should start with a clean TWS install which would also mean cleaning out his registry. Based on what you have said said his system seems fine. When was the last time you cleaned up your registry ?
Thanks for the reply. For one chart it might not be an issue, but I run 4 monitors, 24 charts, 2 scanners, newsfeed and watchlist. Some tickers take a lot of time to load such as APPS/SRNE. Do you see that issue as well? You mind trying to load these tickers for me and see how long it takes for the chart to load them? Would be much appreciated
With a new TWS update I witnessed a slowness several months ago. I closed the new module (about videos) in classic TWS by clicking on the bottom left icons. Everything was way faster after.
People seem to be misunderstanding. We're talking about lag from so many charts being open. I also rock about 26 charts open at same time. 16 of them being individual stocks. Then two group of 4 charts tracking 2 stocks with 4 different time frames open (1min,5min,15min,daily). With 1 to 2 indicators on each chart. If I use tws with only 4 charts of course it works better. But as you get to the higher end something just boggs down. And as I mentioned earlier there's a unique problem to linked charts where one time frame will load and the others will lag or not load at all. There's something that happens when requesting multiple lines of chart data simultaneously for the same ticker. I'll have to start recording my trading sessions again to demonstrate the issue to people.
Yes the same happens to me, some charts will load on one timeframe but not on other timeframes. That's why maybe I was thinking a super fast CPU with 12 cores might solve the issue. Are you using other softwares or just TWS?
What's your average internet speed while connected to TWS ??? Also, what's the minimum requirements by TWS for the internet speed ??? You're using TWS via WiFi or Ethernet direct line ??? I only ask the above because I know someone using TWS which a high end computer and he simply changed his internet provider with speed including going from 120 mpbs to 400 mpbs (WiFi)... That slowness when loading a new chart...disappeared on WiFi. No slowness when connected via Ethernet that gives him 650 mpbs. Simply, its either your computer (you mentioned someone gave it to you) because it doesn't sound like its dedicated to trading as in you're not using it for anything else or its your internet provider. Have you tested TWS with just one chart loaded and then load a 2nd chart to see if the same slowness appears and/or the slowness appears on certain timeframes only ??? Then keep adding charts...3rd chart, 4th chart until you see the slowness appears. You'll then no the limitations of your number of charts you can have with your current computer system. wrbtrader
Yeah...think or swim and I have that running with 26 charts and I can switch tickers and charts are populated instantly.
I have internet subscription of 60mbs and I am using Ethernet. I guess I Should increase my speed. Yes I think my PC can certainly be a factor to why TWS is slow specially it is old and my brother was using it for gaming as well. I just tried on my other laptop which is also not the best but is a i7-8750H with 16GB DDR4. It does bug a bit when loading/zooming charts specially giving me "Attempting to retrieve data" I guess for TWS you need a really powerful PC unlike other softwares that can run on lower PC requirements. Thanks for your help
