(I logged in via Help per your instructions to repost; Also added $ to my SC Direct account) How can 2 instances share chart data built from 2 different feeds? Can 2 instances assist each other with heavy analysis from different timing, markets, bars sizes and data storage time unit (1 second vs tick)? This would overcome computer limits I have reached. Your purpose of instances seems to be: 1) Allow specialization of market data server, or 2) Allow trading from different accounts (or both simultaneously). Example: I need one instance to use tick-by-tick for inside-bar studies and different time frames/ start times (by TCP/IP asynchronous communication of instances?). The other instance does heavy 51 charts+10 spreadsheets processing with 1-second data storage. Such 51 charts-instance can't handle tick-by-tick processing (I think). The computer is at limit. The ability to use different start times, time frames (bar length) and numbers bars could give a cross-check. Different start time of charting gives different (useful) results. Cross-market analysis is also useful. If chart or spreadsheet data sharing worked, I would eventually use about 3 instances this way. (The Space Shuttle used this approach- 2 different hardwares, 4 computers cross-checking). This might be by: a) an Overlay Study from other instance, or b) sharing a single spreadsheet with 2 sheets accessing each other (Sheet would be instance#-Chart# ?), or c) one instance use a new "data server" mode to send chart-study results to overlay on a target instance chart (like packet headers with instance#-chart#-study# prefix). I'm guessing you all thought about dividing computer labor-resources for heavy demands, since you worked to utilize threads. |

This is definitely supported just by using another instance and using the DTC Server. This is fully documented on this page here: Using DTC Server for Data and Trading in Another Sierra Chart Instance Each instance can use a different Intraday Data Storage Time Unit: https://www.sierrachart.com/index.php?page=doc/DataSourceSettings.php#IntradayStorageUnit There is no ability to share study data. Only the historical and real-time market data. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
