I already read the page about subinstance. Just to make sure, for better performance , I should have 1 Data folder per subinstance , is that correct ? And this : I always use another folder for my data than the main folder for all my instances. But Each time I close everything and reload sierra Chart. I have to reselect the data folder and reclick the Always Use Data folder within main folder. Is that normal ? thanks in advance. |

I am seriously confuse about what to do now.... Just to be more specific, I am using IB as my broker , Your Equity feed as my data provider. I dont see the M on the subfolder chart ticker. I can never Change the data folder of my subinstance as they reset to default each time I load them. I try to find DTC Protocol Server >> Enable DTC Protocol Server for the main instance , cant find it. On my subinstance , i try to change port like in the example , does seem to change anything. Generic Sub-Client Server Address: 127.0.0.1:11094 Historical Data Server: 127.0.0.1:11095 When I do file and find for stock , it does not get any usefull result. I just want to understand how to do it so it will be fast and reliable. Do we use the data in the main folder ? so we dont have to download it for each subinstance ? or we have to copy the main folder data ? or what exactly. now it seems to download all the time. thanks in advance.

To start with, do NOT change the data folder for the sub-instance. This will only cause problems. Each sub-instance needs to have its own data folder. All you should need to do is to open the Sub-Instance and it will automatically connect to the primary instance to get the data. There is nothing you should do with regards to this. You will not see the [M] symbol in a Sub-instance as it is not natively getting the data from our servers, but as long as your Primary Instance is getting the data from us, then the sub-instances are as well.

I try to find DTC Protocol Server >> Enable DTC Protocol Server for the main instance , cant find it. The documentation on this page is now up to date:Using DTC Server for Data and Trading in Another Sierra Chart Instance On my subinstance , i try to change port like in the example , does seem to change anything. Regarding this, do not change these settings in the Symbol Settings for symbols.

Will copying the main data folder in each subinstance help for ticker update ? and another problem I have is that my main Sierra chart folder is on my C drive . and I am using my E drive for data. But when I put my Subinstance in a diferent data folder on the E drive , each time i restart them , they go back to have the Check mark in the Use the data folder in the main folder automaticly. Is that a bug ? I am using Crossover on a mac , maybe its only because of the mac usage. ( but it works fine on my main instance. ) thanks. |

Look at what was said in post #3. You cannot change a sub instance data folder. There is no problem. It must remain as it is. Do not change it. It will not work properly and you will cause problems Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

How much data it take on the subfolder ? Is it the same as the main folder ? do I need to copy my Ticker data files ? How to have all the subinstance ticker update without having to download ? Looks to me like the subinstance are downloading their own data from the data feed. I upload a picture of my 4 main. you can see the Data they use. Its all ticker that I already have in my main data folder ( but its on another location not the sierra chart folder ) But still , when the instance are create , they copy all the require files to have my chartbook, trading preference and Study preset setup. I am asking all this because I realize its faster with multiple instance. And from what I will do , I will require around 8 of them. And because of mac , I have to place my Main folder on my main Hardrive : and its only 256 GB. That is why im using an 1 TB SSD for my data folder. I just post another picture showing that my data folder on subfolder is getting bigger too. ( that is why I ask if I should copy my main folder to the Subinstance. ) and I just wonder If the data from the subinstance is getting it directly from the Main data or it download it from the server ? That will help me understand if I need to update all ticker on all subfolder with the Global settings - intraday file update. Date Time Of Last Edit: 2021-02-11 16:24:30

You can place the main SierraChart folder (and subinstances) on the 1 TB drive, it does not have to be drive C. That way everything can be on your biggest drive and work as intended. You may need to update the Data Files Folder in Global Settings>>General Settings. |

I am using Crossover to Use Sierra Chart under MacOS. Its a little bit complicated to change the main folder to the external hard drive. That is why i would like to only use the data folder outside the main folder. But If this is too complicated , I will have to do the other option. I really want to know if I have to copy my data folder from my main folder to the subsintance too. Because with my type of equity trading , I am browsing at least 100 ticker per day and I need it to be update on all instance as most as possible. I just want to understand how it work and the Process I will have to do to make if faster to laod all chart on any given instance. Right now I am using 6 instance as it split the ram load and its much faster like that. ( but I am using all in the same data folder waiting for answer from here. ) thanks in advance. |

When you first create the Sub Instance, everything you need is copied, except the data files. Only the data files that you need will be downloaded when you select a symbol or open a chartbook. |

Is the download done from my main folder or from the data server ?

I just change my computer for a Windows 10 one last weekend. Now , my only question left is , When I create new Sub instance, Can I copy the data folder of the main instance in the Sub instance data folder , to remove loading time and to make the Ticker change on chart work ?

When you create a new Sub-Instance the data from the main folder is automatically copied to the sub-instances Data folder. There is nothing you need to do at any time in terms of moving data between instances. The sub-instances take care of getting the data they need.

Ok . but the problem is that with Support Symbol entry from chart Window options When you did not load the Ticker at least one time, it will not send you to the right Ticker. What is the way to fix ( as I delete and recreate my subinstance often ) or its not possible to fix ? |

You can still enter a symbol using the keyboard even if a data file does not exist, you just have to type in the entire symbol name.
