This way, if you already have data from yesterday downloaded to your system, your computer doesn’t need to request yesterday’s data again. It can find yesterday’s data locally stored, and then ask TradeStation’s severs for the new data that you haven’t yet downloaded. Where does TradeStation store all of that downloaded data? That’s where the Cache comes in. The Cache is a set of databases that TradeStation creates and maintains, typicially stored in your TradeStation program files directory. 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. 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. If those storage files grow to be very large, then they can become a lot to handle. It’s not uncommon to find caches holding files that are many gigabytes in size. So many TradeStation users feel that they can get better performance by occasionally clearing out the cache. That is, clear out all the old downloaded data and let TradeStation build them back up again. 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. 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. #TRADESTATION 9.5 SOFTWARE DOWNLOAD DOWNLOAD# In this case, you may notice a PD symbol at the upper left of a chart, indicating that a Pending Data condition exists as TradeStation is awaiting the delivery of more data for that chart. Don’t worry, it doesn’t take too long, but it’s long enough to notice the delay. Having a healthy cache can greatly speed up the full loading of your charts because the historical data is readily available on your computer. #TRADESTATION 9.5 SOFTWARE DOWNLOAD FULL# #TRADESTATION 9.5 SOFTWARE DOWNLOAD DOWNLOAD#īut when that gets too big, it can be burdensome.#TRADESTATION 9.5 SOFTWARE DOWNLOAD FULL#.
