I spent quite some time investigating why I kept getting "Max number of tickers has been reached 101" error, which made me not able to use NT to trade IB TWS.
In NT, I created two workspaces, one is called "DailyExport", in which I created a few daily charts, another one is called "Defult", in which only one intraday 5min chart is open.
I did not realized that if there are multiple workspaces shown in workspaces menu, they are all opened when NT starts. The check mark only means that workspace is actively shown on screean.
Anyway due to my misunderstanding, when NT starts, both workspaces are open, therefore NT requests hsitorical data for all instruments in my "DailyExport" workspace.
Because I created that "DailyExport" workspace yesterday, the last trading day of the data series of all daily charts is set to "4/23/2008". The detailed descript of this issue is in this post:
So today when I opened NT, all daily charts in the invisible "DailyExport" workspace showed data up to yesterday.
Now it comes the big problem. Whenever I click "Connect" menu to connect NT to my IB paper trading account, in NT Log window there are multiple Max number of tickers has been reached 101 error message shown up.
Because there are only about 13 daily charts opened, the # of tickers should never reach the 100 limit.
This issue can be reproduced each time following my above description.
So I believe there must be something wrong in NT.
BTW, I manually edited each daily chart setting to modify the last trading day to today's date and the error 101 did not show up. When I changed it back to yesterday's date, 101 message showed up again. (However I only tested this once (change them and change them back).
There might be a few conditions need to be met: enough number of daily charts (> 10?), last trading day in data series format window is set to yesterday.
