Hello,

After working through the helpguide and forum I know how to draw a line working with currentbar, startbarsago, starttime, barssincopen, ...

but I can´t find out how to have eg a line from a low of a bar where occurred a conditon to the high of a bar where occurred another condition. I can not use for this startbarsago nor starttime.

How can I have for Drawline the startpoint and the endpoint for the line by conditions please? (eg starting the bar where is the Bollinger-Low and ending at high of the bar where a cross SMA with upper Bollinger occurs)

Thank you
Tony

Hello tonynt,

Thanks for your post.

In general terms what you would do is to save the bar number of the bar when/where the low occurred and save the bar number of when/where the high occurred. You would save the bar numbers into integer variables. You can then use these variables to set the start and end barsago requirement of the DrawLine() method. You would do this by subtracting the low bar number from the CurrentBar and subtract the high bar number also from CurrentBar.

Hello Paul,

thank you for your reply. This is exactly what I intend to do and found out in the forum. But there is one stept I can not do and this is "save the bar number of when/where the high occurred".

Can you post me this one line please?

Thank you
Tony

Hi tonynt,

Thanks for your reply.

In general it would be something like:

if (your condition for low bar)
{
lowBar = CurrentBar; // save current bar into the integer variable lowBar
}

if (your condition for high bar)
{
highBar = CurrentBar; // save current bar into the integer variable highBar
}

You would declare the integer variables lowBar and highBar in the variable declaring section.

Hello,

thank you for your reply. I could do this workaround but I have a problem with my
DrawLine("up", false,CurrentBar-lowBar, Low[CurrentBar-lowBar],CurrentBar-highBar,High[CurrentBar-highBar], Color.Green,DashStyle.Dash,3);

It occurred that the line started where condtion is true first time (days ago) and not in current session when the condition is true. And also it occurred that the line was moving with every new bar(?). What do I have to change please so that the line starts with the bar of most recent condition true and the line ends with the bar of most recent condition and the line is fixed there untill I remove it in the script with new condition true.


Thank you
Tony

Hi Tony,

Thanks for your reply.

With the tag name of "up", there will only be one line shown and it would be the latest drawn. From your description that would suggest that your code is not correctly detecting the conditions you are looking for. I suggest that you add print statements into your conditional statements to understand where lowBar and highBar are being set.
