Prediction & Measurement

What this page is

The seventh and last rail button is Prediction and Measurement, with thirteen tools in four sections. Measure is one of them now: it had a button of its own, holding nothing else, sitting directly under a section already called Measurement — so it was moved into that section, at the end. Nothing about the tool changed.

The Projection section holds Long Position and Short Position. Both take three clicks — entry, target and stop, in that order. The tool then shades the reward band green from entry to target and the risk band red from entry to stop, prints the three prices, and prints the reward-to-risk ratio above them.

The Dummy Candles section holds Forecast, Bars Pattern and Ghost Feed — the three tools that draw price action that never happened. Forecast takes three clicks and is the plainest: a starting point and two projected outcomes, drawn as a solid upward arrow and a dashed downward one, each labelled with the percentage move from the start. It draws arrows rather than candles, and sits under this heading because it answers the same question the other two do.

Bars Pattern takes three clicks and copies real bars. The first two pick a range of the chart’s own candles; the third says where a copy of that price action should be pinned. The copy is shifted in price so that the first copied bar opens exactly at your third click, and it keeps the original shape in the original rupees — a five-rupee range stays a five-rupee range. A dashed marquee stays over the range you copied from, with a faint line joining it to the copy, so you can always see what the copy is a copy of.

Ghost Feed takes two clicks and invents a continuation. The first click starts it and the second says how far ahead it should run and where it should end up; the tool then walks a run of synthetic candles from one to the other. Their size comes from the real bars’ own fourteen-period average true range, so a stock that moves one percent a day gets one-percent-a-day candles, and the last one closes exactly on your second click. Every candle in this section is drawn faded, dashed and captioned, so it can never be mistaken for the market.

The Volume-Based section holds two tools that read the actual bars rather than just your clicks. Anchored VWAP takes one click and draws the volume-weighted average price of every bar from that point forward, which is the average price everyone who has traded since then has paid. Fixed Range Volume Profile takes two clicks and draws a sideways histogram of how much volume traded at each price inside that span, with the point of control — the busiest price row — marked in red and the seventy percent value area shaded.

The Measurement section holds six tools. Three are rulers that differ only in what they report: Price Range gives the price change and the percent change, Date Range gives the number of bars, Date and Price Range gives both. All three take two clicks and shade the box between them, tinted green or red by the direction of the move. Projection and Protractor take three clicks each. Projection measures a leg and repeats it from a third point — the measured move. Protractor reports the angle between two legs at a vertex, and each leg’s slope in price per bar beside it.

Measure, last in the section, is the quicker and rougher version of those rulers: two clicks, a dashed box, and a floating readout with the price change, the percent change and the elapsed time in days rather than bars.

Why it helps you

When to use it, and where to find it

• Before placing an order, using Long Position or Short Position at the prices you would actually use.
• Right after a decisive event — a results day, a gap, a major low — is the moment to anchor a VWAP to it.
• When a stock has spent weeks going nowhere and you want to know at which price inside that range the volume really was.
• When a move has completed one leg and you want a target for the next, which is what Projection exists for.
• Any time you find yourself estimating a percentage in your head. Two clicks with a ruler is faster and correct.

Try it — a short walkthrough

1. 1
   Size a trade in three clicks

   Open the seventh rail button and choose Long Position. Click your entry, then your target, then your stop. The green and red bands appear with Entry, Target and Stop prices on them and the reward-to-risk ratio printed above.
2. 2
   Adjust the stop and watch the ratio move

   Press Esc, click the object and drag the stop handle. The bands and the printed ratio recompute live, which is the fastest way to find out whether the trade works with a stop you could actually live with.
3. 3
   Repeat a leg with Projection

   Choose Projection under Measurement. Click the start of the completed leg, then its end, then the point the next leg begins from. The leg you measured is drawn solid with its price change, percent and bar count written along it, and the ladder at 0.618, 1 and 1.618 of that leg is drawn forward from your third click with the target price on the 1 line.
4. 4
   Copy a piece of price action

   Choose Bars Pattern, drag across the range of candles you want to reuse — first click one end, then the other — and click where the copy should start. The copy appears in the chart’s own up and down colours but faded and dashed, captioned with how many bars it holds.
5. 5
   Anchor a VWAP to an event

   Choose Anchored VWAP and click once on the bar the event happened. A single line is drawn from there to the right edge, tagged VWAP, averaging every bar since by volume.
6. 6
   Measure without leaving a mark

   Open the last rail button, scroll to the Measurement heading, and choose Measure — the last tool in it. Click the two ends of the move and a dashed box appears with the price change, the percent change and the elapsed days. Select it and press Delete when you are done.

Every part, up close

The Chart page — the last rail button holds the position and measuring tools. Each part with a close-up of the real screen; the numbers match the dots on the picture.

The bottom button

Prediction and Measurement is the seventh and last button, and everything on this page is behind it — including Measure, which had a button of its own until 2026-08-31.

2

Entry, target, stop

A position box is three clicks on the candles, and the reward-to-risk figure it prints is arithmetic on the prices those clicks landed on.

Where a trade is real

A Long Position box changes nothing and costs nothing — the Paper Trading tab under the chart is where a plan becomes a recorded trade.

Reading the numbers

• Long Position — 3 clicks: entry, target, stop. Green reward band, red risk band, the three prices printed on their lines and the reward-to-risk ratio above.
• Short Position — 3 clicks: entry, target, stop. Identical construction with the profit side inverted.
• Forecast — 3 clicks: origin, upside projection, downside projection. A solid arrow to the first and a dashed one to the second, each labelled with its percentage move from the origin. Arrows, not candles, despite the heading it sits under.
• Bars Pattern — 3 clicks: two ends of the range to copy, then where the copy starts. The copied candles are shifted so the first one opens at the third click and are drawn faded and dashed in the chart’s own up and down colours, captioned “Bars Pattern” with the bar count. A dashed marquee marks the source range and a faint line joins the two. Copies are capped at six hundred bars; past that the caption reads the count with a plus sign.
• Ghost Feed — 2 clicks: where the run starts, and where it should end. The number of candles comes from how far apart the two clicks are on screen, up to four hundred; their size comes from the fourteen-period average true range of the real bars, and the final candle closes exactly on the second click. A dashed line shows the drift you asked for and the block is captioned “Ghost” with its bar count.
• Anchored VWAP — 1 click. The volume-weighted average price of every bar from the clicked bar onward, drawn as a single line with a VWAP tag at its right end.
• Fixed Range Volume Profile — 2 clicks. A horizontal histogram of traded volume by price inside the span, split into buying and selling, with the point of control in red and the seventy percent value area shaded.
• Price Range — 2 clicks. A shaded box with a vertical arrow down the middle, reporting the price change and the percent change. Tinted green when the move is up and red when it is down.
• Date Range — 2 clicks. The same box with a horizontal arrow, reporting the number of bars in the span.
• Date and Price Range — 2 clicks. Both readouts at once, stacked.
• Projection — 3 clicks: the start of the leg, its end, then where the repeat begins. The measured leg is solid and carries its price change, its percent and its bar count written along it. Three dashed levels run forward from the third click at 0.618, 1 and 1.618 of the leg, each labelled with its ratio and the price it lands on, and the 1 line — the measured move itself — is drawn heavier with the target price at its far end. Green when the measured leg rose, red when it fell.
• Protractor — 3 clicks, and the first one is the vertex. The angle between the two legs is drawn as an arc and printed in degrees on the bisector, and each leg carries its own slope in price per bar written along it.
• Measure — 2 clicks, last under the Measurement heading. A dashed box with the price change, the percent change and the elapsed time in days.
• Only Projection and Protractor fill a region here, so they are the only two tools in this flyout with background colour, visibility and transparency controls. Everything else either draws lines and glyphs, or shades in a colour that is part of its reading — a position tool is green above the entry and red below it, a range ruler is tinted by direction, and a volume profile’s rows are ink rather than a fill. Those controls used to be offered and could not change a pixel, so they were withdrawn.
• The reward-to-risk figure is the distance from entry to target divided by the distance from entry to stop. It is derived on every repaint and never stored, so moving a handle always gives you the current answer.

What it does not do

• Forecast projects nothing. It draws two arrows to prices you clicked and labels them with the percentage from your starting point. Nothing in it is a prediction, and it should never be presented as one.
• Ghost Feed is a drawing, not data. The candles are generated around the line you drew, at a volatility borrowed from the real bars, and they are deliberately faded, dashed and captioned “Ghost” so a screenshot cannot pass them off as market history. They are stable — the same object always redraws identically, on this machine and after a reload — but stable is not the same as real.
• Bars Pattern copies real candles into a place they never traded. Every bar in the copy came off the chart’s own series, so nothing about it is invented, but it is still a picture of the past pinned on top of the present. Do not read the copied candles as a level.
• Both dummy-candle tools measure from the bars the chart is currently showing. During replay that is the revealed part of the series only, so a copy or a ghost placed mid-replay is scaled by what has been played so far.
• The Protractor’s degrees are a screen measurement and nothing else. A chart has rupees up one axis and bars across the other, so an angle between two legs belongs to the current zoom, the pane height and the price-scale mode — zoom in and the same two legs read a different number. That is exactly why the tool also prints each leg’s slope in price per bar, which is computed from the anchors themselves and does not move when you do. Quote the slope, not the degrees.
• Projection repeats a leg; it does not forecast one. The 1 line is arithmetic — the price change you measured, added to where you said the next leg starts — and the 0.618 and 1.618 lines are the two multiples that most often get talked about. Nothing checks that the leg you measured was meaningful.
• Anchored VWAP is computed from the bars currently loaded on the chart, so an anchor placed before the earliest bar you have will start from the oldest bar available rather than from the date you meant.
• Fixed Range Volume Profile splits volume into buying and selling by the direction of each bar, which is an approximation. The floor sheet is the only exact record of who traded, and it settles after the close.
• Date Range counts bars, not days. Over a weekend or a market holiday there are fewer bars than calendar days. Measure, four rows below it in the same section, does the opposite and reports elapsed days from the raw timestamps, so the two will disagree — deliberately, because they answer different questions.
• The position tools are drawings, not orders. Nothing here reaches a broker, nothing is being watched for you, and no alert fires when a price is reached.
• All thirteen tools can be drawn on the Chart page, so nothing in this flyout is greyed out. If the engine ever could not draw a tool, its row would be disabled with a tooltip saying so.
