Sometimes, for whatever reason, I like to draw horizontal price lines as reference price points. For example:

=========================================================

dow 30
chart-time is 30

draw price line at ma(15)
draw price line at ma(15) multiply by 1.00500
draw price line at ma(15) multiply by 1.00475
draw price line at ma(15) multiply by 1.00450
draw price line at ma(15) multiply by 1.00425
draw price line at ma(15) multiply by 1.00400
draw price line at ma(15) multiply by 1.00375
draw price line at ma(15) multiply by 1.00350
draw price line at ma(15) multiply by 1.00325
draw price line at ma(15) multiply by 1.00300
draw price line at ma(15) multiply by 1.00275
draw price line at ma(15) multiply by 1.00250
draw price line at ma(15) multiply by 1.00225
draw price line at ma(15) multiply by 1.00200
draw price line at ma(15) multiply by 1.00175
draw price line at ma(15) multiply by 1.00150
draw price line at ma(15) multiply by 1.00125
draw price line at ma(15) multiply by 1.00100
draw price line at ma(15) multiply by 1.00075
draw price line at ma(15) multiply by 1.00050
draw price line at ma(15) multiply by 1.00025
draw price line at ma(15) multiply by 0.99975
draw price line at ma(15) multiply by 0.99950
draw price line at ma(15) multiply by 0.99925
draw price line at ma(15) multiply by 0.99900
draw price line at ma(15) multiply by 0.99875
draw price line at ma(15) multiply by 0.99850
draw price line at ma(15) multiply by 0.99825
draw price line at ma(15) multiply by 0.99800
draw price line at ma(15) multiply by 0.99775
draw price line at ma(15) multiply by 0.99750
draw price line at ma(15) multiply by 0.99725
draw price line at ma(15) multiply by 0.99700
draw price line at ma(15) multiply by 0.99675
draw price line at ma(15) multiply by 0.99650
draw price line at ma(15) multiply by 0.99625
draw price line at ma(15) multiply by 0.99600
draw price line at ma(15) multiply by 0.99575
draw price line at ma(15) multiply by 0.99550
draw price line at ma(15) multiply by 0.99525
draw price line at ma(15) multiply by 0.99500


=========================================================

These lines are 0.025% apart from each other centering on MA(15) so they could appear as one price band with no spaces in between. Because of that, the legend took way too much space on the chart. Is there any way to suppress chart-legend at all?

Any other suggestions to accomplish the same end result if legend suppression is not possible at this moment?

If those legends are taking up too much space vertically as in overlapping the volume and other subcharts just widen your main price chart so all of the legends are in it.

If those legends are taking up too much space horizontally make some set variables with short names for your ma(15) calculations and line draw those variables.

I don't know of any way to get rid of legends in SF

Thank you Ed.

I've been thinking about another possible enhancement/feature request specifically for drawing HORIZONTAL price lines such as:

draw price line at ma13, etc. where ma13 would be a user variable defined as:

set{ma13, ma(13}

With these user defined variables, would it be nice to add the feature

PlotWeight{ma13, 0.001}

This weight dictates the thickness of this line on the chart, so that 0.001 would be 0.1% of the chart's height. This way, if someone wants to draw another horizontal line for MA5 at 0.003 thickness level, the 2 would appear distinctively on the chart because 0.003 is exactly 3 times as thick as 0.001!

(Would be super nice if PlotColor{ma13, blue} is also added to one's arsenal!)

Is this possible to do? Easy to implement?

Any comments/thoughts?

It is nice to have dreams/wish list but in the 3+ years I've used SF I know of only 1 feature addition and 2 major elements discontinued.

My belief is their programming staff is minimal and operates in a maintenance/help mode only.

My wish is that a consortium of SF users buy the company/software rights, hire a few programmers, maybe raise the fee by $5 and really start to make lots of improvements some of which would probably be very, very easy to do.

Still for the price, the data, and the features, SF is quite a remarkable product!

Ed,

Your observation is probably 100% correct; I often wondered myself where did all those prior active users/forum participants go (after making and pocketing their millions in trading profits? Maybe they have all retired to a beach somewhere out of this world)

In the last 3 years or so, I've finally embraced the idea of: SEE MORE; JUDGE LESS. I moved away from the idea of searching for the killer filter altogether; instead, I eyeball every ticker symbol that moves up more than 3.5% during the day (along with a few minimal constraints on avg volume, avg close, min market cap, etc. ) in order not to miss any possible opportunity.

In order to do just that, I used "dow 30" as if it's a real lab to test any ideas that came to me. But it was only during COVID-19 era did I realize the importance of selecting/using horizontal lines as "reference prices". In reality, it's probably a lazy person's visualization and back-testing rolled into one.

But I am not yet willing to "buy SF" from its current owner. Despite a few shortcomings, SF meets 95%+ of ALL my needs for trading and charting. Here is a somewhat simplified illustration, but it gives me the clear indication of where each of the Dow 30 stocks stands on any given day (the weekly view is even better.)

Fetcher[dow 30
chart-time is 36 days /* 1/7 of the assumed 252 trading days per trading year*/

/* Draw EMAs on price plot */

draw ema(3)
draw ema(6)
draw ema(10)
draw ema(15)
draw ema(22)
draw ema(32)
draw ema(45)


/* Draw Horizontal Reference Price Lines */

draw price line at ema(3) 1 day ago
draw price line at ma(3) 1 day ago
draw price line at ema(4) 1 day ago
draw price line at ma(4) 1 day ago

draw price line at ema(3) 3 days ago
draw price line at ma(3) 3 days ago
draw price line at ema(4) 3 days ago
draw price line at ma(4) 3 days ago

You are in good company.
In later years of his stay at sF, TheRumpledOne was a big advocate of straight lines
as opposed to what he called the squiggly lines of many indicators.

@Cheese

Thanks. Only wish there is a way to easily control thickness level of these horizontal price lines, much the same way as "draw ma/ema envelopes" on the chart.

These horizontal lines constantly remind users whether the underlying stocks range bound or not. cf:

Fetcher[dow 30

Wouldn't it be super nice if a single line of "Draw price envelope at ma(20, 0.5, 21, 0.5)" could replace a section of codes above?

In addition, 2 more features could or should be added:

a. PlotWeight{user_variable, value} /*value is between 0.0001 to 1.0000, which is the ratio between line thickness and the entire plot height.*/

This has the benefit of UNIFORM thickness across all tickers, regardless of the volatility


b. PlotColor{user_variable, ColorName} /*Color name can be limited to just a few colors: Red, Blue, Pink, Orange, Black, Green, etc.*/

A total of 10 to 12 color names is sufficient to distinguish between different horizontal lines so the meaning could be instantaneously apparent. Visual clues have their maximum effect/impact when their significance is immediately understood WITHOUT laborious study. Stockchart.com, by contrast, offers exactly 12 color names in their color drop down box. This total # of color choice is not only reasonable but also highly practical, imho!

@styliten

I'm not too particular about more formatting capability.

What I really like about your FILTER #1 is that you've found a VERY CLEVER way
to make support and resistance move DYNAMICALLY with date offset.

THANK YOU for sharing FILTER #1.
I still have to do more study of your filters #2 and #3
