TradeStation seems to be pretty smart about this, in that it will download a page full of the newest data first, so you can see the chart quickly, and in the background, download the historical data. If you completely clear out your cache, TradeStation will need to download ALL of your data again – which it will do – it just takes a bit longer to get the data from the server to your system. That is, clear out all the old downloaded data and let TradeStation build them back up again. So many TradeStation users feel that they can get better performance by occasionally clearing out the cache. It’s not uncommon to find caches holding files that are many gigabytes in size. If those storage files grow to be very large, then they can become a lot to handle. All the new data it downloads gets stored in the cache, so the next time the chart is loaded, it doesn’t have to request that data from the server again.Īs you can imagine, after a while, a LOT of data gets stored. When TradeStation draws a chart, it pulls all known data for the chart from the cache, and whatever it doesn’t have, it requests from the TradeStation servers. The Cache is a set of databases that TradeStation creates and maintains, typicially stored in your TradeStation program files directory. Where does TradeStation store all of that downloaded data? That’s where the Cache comes in. It can find yesterday’s data locally stored, and then ask TradeStation’s severs for the new data that you haven’t yet downloaded. This way, if you already have data from yesterday downloaded to your system, your computer doesn’t need to request yesterday’s data again. So TradeStation saves all the data it downloads, and then only requests new data from the server. You can imagine that’s quite a bit of data, and if every TradeStation user had to download the data for all charts every morning, that would take a lot of time and effort for their servers to provide it. What is a cache? You probably know that all of the market data gets downloaded to your system. But use it with care, and it should only be done by someone with plenty of confidence in using computers and in using and restoring TradeStation. It’s can be a bit complex to do this, but it’s rather simple once you try it. If you have been told to “try clearing the cache” in TradeStation, you may not know what that means. RESEARCH CLEARING YOUR TRADESTATION CACHE FROM MULTIPLE SOURCES BEFORE ATTEMPTING TO TAKE ANY STEPS IN CLEARING YOUR CACHE ONLY ATTEMPT THESE STEPS IF YOU ARE CONFIDENT WITH WORKING WITH COMPUTERS.īASE CAMP TRADING WILL NOT ASSIST YOU WITH RECOVERING FROM ANY ERRORS THAT OCCUR DUE TO ATTEMPTING ANY OF THESE PROCEDURES.ĭO NOT EVEN THINK ABOUT DOING ANY OF THESE STEPS UNLESS YOU HAVE A FULL BACKUP OF YOUR TRADESTATION FILES, INCLUDING INDICATORS, STRATEGIES, WORKSPACES, DESKTOPS, ETC. AND YOU KNOW HOW TO RECOVER YOUR TRADESTATION CONFIGURATION USING THEM
