We may be misunderstanding each other.
a) If what you are asking for is keeping the line chart up-to-date with the prices that arrive to the TWS (these are not tick-by-tick) because it does not work, we'll fix it if it is indeed broken. We have this for the bars.
b) If what you are asking for is real-time tick-by-tick feed into the line chart, we can't give you that. We don't have that for the bars either.
Is it a) or b)?
(BTW, if our software detects that you are pressing the refresh every 2 seconds, it will stop giving you backfills for the rest of the day).

Thanks for the feedback.
I meant "A". I am aware that IB doesn't deliver true "tick-by-tick" information. My reference is to the data that IB does deliver. The bars/candlesticks update with each price change. The one-day one-minute line charts do not.
Much thanks in advance if you can finally get this corrected!

Thank you very much Mr TGM.
Varying the macd from simple-to-exp: we have both of them separately, do you need to be able to flip between the 2?
Colors: yes, in the next beta.
Second login: could you please clarify your request?
Position management: It is a VERY big project. I don't believe we started yet.

Indeed, the desire has been heavily expressed mostly by misinformed posters, who believed that charts compete with order routing and market data. They do not compete; I hope I have successfully put that topic to rest a few posts ago.

Well this is not exactly what API traders want.
We want to have a GUI and a separate core logic because API traders just don't need TWS GUI (and maybe they also don't like it who knows...)
So if there could be a way to just launch the "core logic" without using CPU cycles and memory for the GUI that would be fine.

In principle I agree, but one needs to take a practical aproach which is to pressure IB to fix whatever issues there are in TWS/server side reliability. I havn't seen any issues with the basic GUI features of TWS that in my view contribute to unreliability.
>> I never said that, it is just not needed for API traders to have TWS GUI opened on the trading machine.
CPU utililization is a non issue. Unless you have a lot of market data lines, TWS CPU utilization is negligable. I'm running TWS with API connected app at the moment. About 10 TWS market data lines (DAX, ESTX50, HSI etc). With TWS minimised CPU utilization is less than 0.5 %. (Linux / Athlon Socket A 2800 with bbout 50 instruments monitored by the API connect app). TWS CPU utilisation really is not an issue. Of course if you use book trader etc etc, things will be different.
Memory use is barely an issue. If 50 Mbyte is an issue then buy some more memory.
My guess is that sometime in the future, IB may drop or reduce the charge for FIX and the streaming market data module that I saw mentioned recently. Just guessing, but I wouln't be surprised if the streaming market data module code is just stripped out of TWS into a separate process, so in all likelyhood not anything new at all.

>> I assume the reason IB says no is because of the FIX API...Providing a lighter TWS API-only version would maybe "kill" their FIX market or at least lower their revenue on this side...
A lighter TWS could be done that way :
On the login screen (and in the INI file) provide a checkbox that allows to launch or not launch the GUI. If not launched TWS would be used to accept API entries and be minimized in the right side of the taskbar (the TWS icon color would change to green/red depending on connectivity issue or not, there should be a way also to know when an order is launched or not, maybe a small animation on the TWS icon when an order is received and when an order is executed). If launched this is the classical TWS GUI (that would be the default choice).
How hard is it to code that ?
