zemuss Posted July 19 Report Share Posted July 19 I was watching the price action on the Simple Portfolio and notice QQQ lagging behind TOS. I am sure this is due to the API. Is there any tweaks that can be done? Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted July 19 Report Share Posted July 19 TS does use a different datafeed. We show the stuff as soon as it comes in. was the lag just bid/ask or last too? Quote Link to comment Share on other sites More sharing options...
zemuss Posted July 20 Author Report Share Posted July 20 all three were lagging. I had TOS and Medved side by side. Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted July 20 Report Share Posted July 20 ok, by how much? 1 second or less, or more? Quote Link to comment Share on other sites More sharing options...
zemuss Posted July 21 Author Report Share Posted July 21 i think it was about a 1 second delay or so.. because some times Medved showed 450.90 for instance and TOS showed 450.65.. Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted July 21 Report Share Posted July 21 the data feed they are providing is 1 second updates, so what you are describing is consistent with that. If you use tick updated datafeed, you would not see that. For example, dxFeed, Tradier. Quote Link to comment Share on other sites More sharing options...
zemuss Posted July 22 Author Report Share Posted July 22 Is Webull or Tradestation Tick Updated ? Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted July 22 Report Share Posted July 22 TradeStation is same 1 sec update. Webull is faster, but their quotes can be a bit flaky. Like no bid/ask. Quote Link to comment Share on other sites More sharing options...
