Drawing lines when using logarithmic scale

[Tartan]

I am having problems when drawing lines on my chart while using a log scale. Perhaps there is something that I am missing?

- The cross hair does not stay at the end of the line I am drawing making it awkward to draw the line
- When I copy the line to create a parallel line then the copied version has a different slope
- I do not seem to be able to extend the line beyond the top of the data. For instance in an upward sloping trend, I would like to project the line beyond the the rightmost point into the future

How can I resolve these issues?

I am trying to use the line function again tonight within a log chart. I am trying to draw an upward sloping diagonal line. But NT7 draws a horizontal line.

The problem that I had earlier cant be replicated, but this new problem now exists.

Hopefully this is clear enough input.

Hi Tartan,

Can you please provide the instrument and period type (1min, 5min, tick chart, etc) you are using for the chart? Thank you.

[Tartan]

The instrument i am using is ES March futures.

Tartan,

Unfortunately I was unable to reproduce. Were you using equidistant charts? Non-equidistant charts? Minute charts or tick charts or maybe some other type of chart?

I am trying to draw trend lines on for the 6E March contract and am getting the same sort of problem. It's never fully consistent.

I am viewing a 60 minute OHLC chart and when I draw a trend line, then copy and paste it to create a parallel duplicate, then move the copied line to another place on the chart. When I do all of this, then the copied line changes slope as soon as I move it.

On this chart, I am able to extend the line to the right of the data set - so this problem is not appearing.

I really think you need to put some time into testing this issue thoroughly since it is such a basic but important task.

Are you sure you are on 7.0.0.6?

[Tartan]

Hi: Yes, I am using 7.0.0.6.

Here is a link to a screencast that outlines my issues.

Note that:
- I created a line and then copied it to create a parallel line. When I move this copied line then it changes slope
- The "tool" of the crosshair (either an X or a pencil depending upon the context) is not aligned with the middle of the cross hair
- I can get the X/pencil to move to the top portion of the chart but cannot get the middle of the crosshair to move to the top portion of the chart.

Josh is out right now but will follow up on this early next week. Thanks for your patience.

Tartan,

I was able to reproduce. We will look into it. Thank you.

I am still having problems with Log charts in NT 7.0.0.8

Below is a link to a video that shows:
- Andrews Pitchfork on a log chart. The lines are not parallel but expand.
- When I copy a line, the copied line is not parallel to the original line.
- When using the fibonacci tool, the fib numbers do not change between linear and log charts. They should.

We will look into, thx.

Tartan,

Your video just shows the end results, but I still do not know how you got to those results. When I tried to reproduce my lines copy as parallel lines and I have no problem with the Andrew's Pitchfork. Please clarify. Thank you.

1)
When I copy and paste a ray on a linear chart, the lines are parallel.
When I copy and paste a ray on a log chart the lines are not parallel.
I would like to create parallel lines on log charts as well as on linear charts.

Of course if I create a parallel line on a log chart it literally maps to a curve on a linear chart and vice versa. And that NT7 is approximating a straight line on a linear scale as a straight line on a logarithmic scale and vice versa. It is ok with me if global sharing of some objects are not well defined.
When it is important I won't share them.

But it would be helpful to be able to draw parallel lines on a log chart.

2)
From the hints earlier in this thread I realized how to manually construct parallel lines. thks.

If I select a ray, copy it, and do not deselect the ray, right clicking on the chart does not indicate that paste is available. Once I guessed to try ctrl-v I got a duplicated line to manipulate. With out a paste prompt in the user interface I was too dense to realize all I needed to do was press ctrl-v.

josh:

try a logarithmic chart that has a wider range.
Maybe a weekly chart over the last year of
something that has at least doubled in value.
The compression from the log chart will be more visually evident.
