@ fotchstecker Thank you for your input.

I guess my question is that when I ran a sample code to test out VWAP, I really didn't see that much difference or benefits with vs without volume consideration:

Fetcher[dow 30

chart-time is 20 days

draw ema envelope(9, 0.05)

draw cema(clri(close multiply by volume, 5) divided by clri(volume, 5), 9) on plot price]



Only in IBM's case did I saw a 1 day difference in timing, everywhere else timing signals seemed to have been almost identical between the simple EMA(9) and VWAP(9).

Did I misinterpret the power of or the formula for VWAP?

Is it really that good? Does SF have an equivalent to that?

Just a thought:

Drawing hma25 vs hma50 vs the inverse of hma25 about hma50:

Fetcher[dow 30
chart-time is 30 days

/******HULL25MA**********/
set{slow1a, cwma(close, 12)}
set{slow1b, 2 * slow1a}
set{slow1c, cwma(close, 25)}
set{val1, slow1b - slow1c}
set{hma25, cwma(val1, 5)}
DRAW hma25 ON PLOT PRICE

/******HULL50MA**********/
set{slow2a, cwma(close, 25)}
set{slow2b, 2 * slow2a}
set{slow2c, cwma(close, 50)}
set{val2, slow2b - slow2c}
set{hma50, cwma(val2, 7)}
DRAW hma50 ON PLOT PRICE

draw cema(hma25 multiply by 2, 1) minus hma50 on plot price]



Hopefully the 3 lines together give better indication of timing.

@ Cheese,

Here is another twist. It seems that day position indicator, when used strategically, can be that perfect intermediary/go between of a shorter and a longer linear regression intercepts.

For example:

Fetcher[dow 30

chart-time is 30 days

/* set up Day Position(0.5, 8) -- the inner core is DP(0.5, 8), in RED */

/* Plz note, when trending one way or another, these outer layers of CEMAS are PARALLEL to the red line */
/*when trend reverses/shifts, the outer layers crisscross each other, creating a more messy picture that can take some time to get used to. */

/* The outermost layer appears somewhat thicker and heavier than the ones in between, which is a very nice visual aid to have. */

set{dp81, day position(0.4920, 8)}
set{dp82, day position(0.4940, 8)}
set{dp83, day position(0.4960, 8)}
set{dp84, day position(0.4980, 8)}
set{dp85, day position(0.5000, 8)}
set{dp86, day position(0.5020, 8)}
set{dp87, day position(0.5040, 8)}
set{dp88, day position(0.5060, 8)}
set{dp89, day position(0.5080, 8)}

and draw cema(cema(cema(cema(clri(dp81, 8), 6), 6), 6), 6) on plot price
and draw cema(cema(cema(cema(clri(dp82, 8), 6), 6), 6), 6) on plot price
and draw cema(cema(cema(cema(clri(dp83, 8), 6), 6), 6), 6) on plot price
and draw cema(cema(cema(cema(clri(dp84, 8), 6), 6), 6), 6) on plot price
and draw cema(cema(cema(cema(clri(dp85, 8), 6), 6), 6), 6) on plot price
and draw cema(cema(cema(cema(clri(dp86, 8), 6), 6), 6), 6) on plot price
and draw cema(cema(cema(cema(clri(dp87, 8), 6), 6), 6), 6) on plot price
and draw cema(cema(cema(cema(clri(dp88, 8), 6), 6), 6), 6) on plot price
and draw cema(cema(cema(cema(clri(dp89, 8), 6), 6), 6), 6) on plot price

/* shows up on chart as green band */

and draw Center Standard Error Band(6,0.20)
and draw Center Standard Error Band(6,0.18)
and draw Center Standard Error Band(6,0.16)
and draw Center Standard Error Band(6,0.14)
and draw Center Standard Error Band(6,0.12)
and draw Center Standard Error Band(6,0.10)
and draw Center Standard Error Band(6,0.08)
and draw Center Standard Error Band(6,0.06)
and draw Center Standard Error Band(6,0.04)

/* shows up on chart as purple band */

and draw Center Standard Error Band(50,0.04)
and draw Center Standard Error Band(50,0.03)
and draw Center Standard Error Band(50,0.02)
and draw Center Standard Error Band(50,0.015)
and draw Center Standard Error Band(50,0.01)]



The 2 Linear Regression bands are placed at the very end only because they then would not appear in the legend area, thus maximizing viewable chart area. If you bothered to rearrange and put them at the very top/beginning of the code, the viewable chart area shrinks due to legend taking up way too much space. Together, the various levels of cemas of Day Position(0.5, 8) serve as support/resistance line groups and this is highly useful when LRI(6) is far away from LRI(50) so that the white space in between are 'mapped' out with meaningful support/resistance lines in between.

Also, unlike MA(20), MA(50) or MA(200), the embedded cemas of Day Position(0.5, 8) never really diverge that much from the underlaying price. So its primary purpose is to show better or even exact timing of potential trade while it may or may not compete successfully with longer term MAs to show bigger trend.

The above pretty much has all the information one needs to make educated guesses in real time!

(PS, SF's chart legend stopped working on this one when Donchian Band is embedded within CLRI.)

Feedback is welcome, as always.

Fell in love with Center Standard Error Bands indicator:

https://www.stockfetcher.com/forums/Indicators/Standard-Error-Bands/96315

This is in fact the LRI envelope that Kevin lamented about lacking:

https://www.stockfetcher.com/forums/Filter-Exchange/Any-chance-of-seeing-a-LRI-Envelope/108033/-1/108037

It is, after all, NOT lacking, but under a totally different name!

The only problem with Center Standard Error Bands at this time is that the MAXIMUM period allowed is 252, unlike LRI that allows maximum period of 300! According to some, the LRI(100) and LRI(300) have special importance in FX trading (on the hourly chart). This discrepancy between LRI and Center Standard Error Bands on Maximum period has been communicated to SF developers numerous times and at this very moment, they are taking another look and see if maximum period for Center Standard Error Bands can be easily upgraded to 300 as well.

If you like CSEB after reading this post, let's beg for Standard Error Band(300)! Have some mercy on us, please!

@ Ed,

Well, if you only draw ma(3) and ma(13) to any ticker, would these 2 lines, together with the candlesticks on the main price plot offer any clues on direction at all?

Now in addition to MA(3) and MA(13), I added a symmetrical line about MA(13) so that this new SL line could join MA(3) and form some kind of loop around MA(13). The loop could come in various sizes and shapes. Does this loop offer more visual clues than the original "half" loop between MA(3) and MA(13)?

Realizing that MA(3) itself may be too close to the candlesticks and thus often interfere with clue gathering, I decided to replicate this MA(3) loop, through extrapolation, a bit further away from the candlesticks to form a somewhat bigger loop. This bigger loop would still preserve much of the shape of the inner MA(3) loop ( shown below in the sample code). It's no different than circulating beltways around larger cities: I-2XX vs I-4xx vs I-6XX vs I-8XX, except in this case the bigger loop closely mimic the very shape of the MA(3) loop in the city core. And just like traveling through these major intersections, extra care and attention is needed as breakouts or fallouts tend to happen at a much greater rate right around the exits/entrances when loops cross over/below MA(13).

Here is the comparison between inner MA(3) loop vs outer Loop:

Fetcher[dow 30

chart-time is 20 days

draw ma envelope (13, 0.1)
draw ma envelope (13, 0.15)
draw ma envelope (13, 0.2)

draw ma(3)

draw cema(ma(13) multiply by 2, 1) minus ma(3) on plot price

set{a1, tsf(ma(3) multiply by 2, 5)}
set{a2, tsf(ma(3) multiply by 3, 5)}
set{a3, tsf(ma(13) multiply by 2, 5)}
set{a4, tsf(ma(13) multiply by 3, 5)}

draw a2 minus a3 on plot price
draw a4 minus a1 on plot price]



The MA(13) envelope is city's Broadway (the city itself is infinitely long, but evolves around its Broadway). Loops are created so that travelers can easily visualize & ANTICIPATE possible exit and entrance points along the Broadway. This way, infinite cities are dissected into manageable segments and each segment can be glanced over quickly for potential trading opportunities.
