Hi there dear friend.
I found this indicator here that plots HLC bars, but it needs some more refinement.
I would like you to check the code, please, to see if it is possible to modify it to:
-Choose number of bars to plot historically (for example: 500, 1000, etc..)
-Fix the options in the indicator to be able to choose the color and width of the close and bars at the same tab. At the moment the inputs tab serves to change to color of close (but does not let you change the width). But you can see that even when black is chosen, it is plotting a gray line. The colors tab allows you to change the width and color of bar. Perhaps you can move the option to choose color and width of the close line to this tab too.
I am attaching image and indicator to this post.
Best regards
