Playback: What is meant by High-resolution data ?

Postby chi jeongki » 08 Aug 2017

When I try to playback, I get the following message.
It pops up when I change playback resolution from "As is (60 tick Bars)" to "Tick by Tick".

The symbol HighResolution is a test symbol I made.
It has imported 1-tick trade data for a day from text file.

Is there higher resolution than 1-tick data.
The millisecond part is fictitous data I attached to original data which has no millisecond part.
I guessed the message was looking for millisecond part, but my guess seems wrong, I get the same message.

Then, does MC.NET looking for 1-minute data and 1-day data?

Further test shows that it might be a bug.
MC.NET was not looking for 1-minute or 1-day data, it just failed depending on the chart data range To: date.

I filed a bug report https://www.multicharts.com/pm/public/m ... es/MC-2295, since I do not know how to attach screen recording in this page.

I got the answer.
It was not a high resolution data, it was session break to session break.
"1 session" or "session break" are not clearly defined in the answer.

I will explain what I found by test.
Suppose, the symbol has historic tick data in Quote Manager, then when you change Playback resolution to Tick by Tick,

1. If time frame is minute, hour chart. even for a day's partial data, there's no error message looking for "high resolution data".
2. If time frame is tick chart, a day's full tick data ( 1 session ?) results in error message looking for "high resolution data".
Adding 1 tick data of next day to the data range, suppressed the error message and worked fine in Tick by Tick Playback.

If we call the vertical line which we see in chart at close of the day as "session break",
then tick chart was looking for 2 session breaks to correctly Playback at resolution "Tick by Tick".
