indicator for highest high daily bars

[rtwave]

hello everyone,


i would appreciate your help with an indicator i'm trying to code in nt.


it is a very simple idea, on a daily bar chart, i would like an indicator that can find the highest high for the last 2 years only (500 bars or so), and then with that numeric value for the highest high, plot a set of horizontal lines. these lines would be plotted at intervals of 10%, the first horizontal line would be plotted at the value resulting of the highest high of the period by a factor of 100% (1), the second one would be the same highest high by a factor of 90% (.9), and so on until 10% and 0%.

if there was a way to plot these lines in different colors each and paint the chart bars that fall between two lines with different colors that would be even better.

thanks a lot, regards.

this will get you started, just create a new indicator, delete everything and copy my code in there.

i only did it for high of the last 500 candles so you would need to add the other lines. Mainly bc i didnt really put much effort in tryin to understand what u even mean

if you have any questions, pls ask. more information is included in the code.

                DrawLine("high"+CurrentBar,false,1,high,0,high,Color.Magenta,DashStyle.Solid,2); // draws a small line over the currentbar with the max high we got from the line above. this line will be updated on every bar ofc, so will eventually become a big one.

                DrawLine("high"+CurrentBar,false,1,high,0,high,Color.Magenta,DashStyle.Solid,2); // draws a small line over the currentbar with the max high we got from the line above. this line will be updated on every bar ofc, so will eventually become a big one.

this code works great and does plot a line at the level of the highest high of the period analyzed.


i have read most of nt's help guides and i think i now know what kind of modifications would generate the set of horizontal lines i was thinking of. it would be one of these possibilities:

DrawLine("high"+CurrentBar,false,1,(high*.9),0,(high*.9),Color.Magenta,DashStyle.Solid,2);

or

DrawLine("high"+CurrentBar,false,1,(high*.9),0,high,Color.Magenta,DashStyle.Solid,2);

or

DrawLine("high"+CurrentBar,false,1,high,0,(high*.9),Color.Magenta,DashStyle.Solid,2);

now, how would it be possible to generate an analog indicator to these horizontal lines? an indicator that generated the following calculation and returned a numeric value:


( price close (0) - lowestlow (500 previous bars) ) / ( highesthigh (500 previous bars) - lowestlow (500 previous bars) )
