Indicator Y-Axis visible range of values not useful

[darmbk]

Hi all,

I have an indicator which can take values between 0 and 100 though most often the values are less than 1. If the value is >1 then the value is not shown on the indicator pane as the range of values shown is 0-1 in increments of 0.2. If the value is <1 the axis seems to zoom in on the value and show no other values on the axis. By this I mean if the value shown is 0.63, I won't see 0.6 or 0.5 above or below respectively as they will be far away at the current axis magnification. This indicator uses calls to the built-in ATR indicator for input. What do I need to do to make sure the Y-axis range is reasonable (show a range of values nearby) and always include the current indicator value?

Thanks,
darmbk.

Hello darmbk,

Thank you for your post.

Can you please provide a screenshot of what you are seeing on the chart?

Additionally, would you be willing to share your script so that I can investigate this further?

Hi Cal,

I have found that the issue is related to Min Bars Required as I am using daily indicators on a 1 min chart.

During the first number of days of data, while there are no daily indicators displaying values (where I was stating that I saw just an axis of values from 0-1), when I print output to a file during these dates, my bespoke indicators report values that are not shown in the chart, perhaps creating averaged data simply from what data is available ignoring that for instance a 14 day indicator has fewer than 14 days data to calculate a value. Would this be correct? So for example, if I use a 14 day MA on a 1 min chart but only have 10 days of data, will the chart show blank but if I print out the same 14 day MA values the indicator will calculate it based on the days of data available even if this is less than 14 days?

So I understand the Y-Axis issue now. I will need to investigate this starting bars issue before I open a forum post on it.

Thanks,
darmbk.

darmbk,

Essentially yes, this is correct.
One thing to note is that you can change the BarsRequired to a lower value, BarsRequired = 1; in the Initialize().

Additionally, you can run a current bar check against the period to ensure the script has enough data before calculating.

Example -
if(CurrentBar < Period) return;

This tells the script to only start running the rest of the code after the current bar has passed the value of Period.

Let me know if I can be of further assistance.
