Two coins per screen

Each price in Two per screen takes the largest type that fits its band, and the row of figures decides how tall that can be. With any figure switched on, the price is held to the ticker's second-largest price size, 41 pixels tall, one size under the price in One per screen, so the figures fit beneath it in the 118-pixel band. With every figure off, the height the row would have used goes to the price instead: the limit becomes the room left under the title, 61 pixels on this screen, and the price can use the largest size, 45 pixels tall.

Under that limit each price is fitted to the width of the screen, 240 pixels, and right-aligned. The two largest sizes also come in a narrower cut, which a price tries before it drops a size. Both bands are the same height, so the two prices share one height limit: two prices of similar length come out the same size, and one that is too long at that size steps down on its own.

Under each price in Two per screen sits one row of figures, the same four the Price Area offers in One per screen, drawn a size smaller. The 24h% stands at the right in the same color as the price, in type 27 pixels tall. On the left, one at a time, comes 24h Vol, Market Cap or Market Cap Rank, starting one size smaller than the percentage so the percentage stays the anchor of the row, and stepping down again if it does not fit beside it with its 22-pixel gap. A figure the ticker has no value for reads "No VOL", "No MC" or "No RNK", and rank always wears its "#", as in "#7".

What each figure means and how the rolling 24 hours work is the same in every layout; see the Price Area on the One per screen page. The same goes for the Show (V/M) prefix switch, which puts a small V or M in front of volume and market cap.

The left-hand figures you switch on share the screen's time equally, in a fixed order: 24h Vol, then Market Cap, then Market Cap Rank. Two figures get half the time each, three get a third. Both coins change figure at the same moment, so the pair always shows the same kind of number, and only the left spot is redrawn: the prices and the 24h% stay still. At the factory settings all three are on, so each gets a third of the 10 seconds a screen stays.

The three moving pictures above are built from the ticker's own frames, the same two coins drawn once per figure, each frame held as long as a ticker set that way would hold it. The figures stop taking turns while the screen is paused, while a message box is over it, and while the address box is up, so a held screen stays still and nothing redraws through a box on top of it.

With the 24h% off and a left-hand figure on, that figure moves to the right edge, where the percentage stood, and starts at the percentage's own size. With only the 24h% on, the left spot stays empty and the row carries the percentage alone. With all four off, the row disappears from both bands, the icon grows back to 47 pixels, and the price takes the freed height, as described above.

The ticker fetches the latest figures for both coins together as a screen comes up, and draws the screen from them. Nothing on the screen is fetched again while it stays up: the left-hand figures take their turns from the same set of numbers. The next screen brings its own fresh fetch. With only one screen of coins, the same screen is fetched and drawn again each time its time runs out. How often the figures themselves change is covered in how often prices refresh.

Each screen stays for the time on the Show Two for: slider under the coin boxes: 10, 15, 20, 25 or 30 seconds, 10 seconds from the factory. The whole screen shares that one time. One, Two and Four per screen each keep a time of their own. The slider applies as you move it, and the new time counts from when the screen on the glass appeared, so shortening it can bring the next screen at once.

Both ends of the range have a reason. Every new screen means a fetch, so 10 seconds is the floor. A screen's figures are not refreshed while it stays up, so 30 seconds is the longest the ticker leaves one standing. The fetch for the next screen starts a little under half a second before the time runs out, so the time you set is about the time the screen is on the glass, not that time plus the wait.

Under the coin boxes, the arrow buttons step a whole screen back or forward, and the pause button between them holds the current screen for up to 30 seconds; when it lets go, the screen finishes the time it had left. Tapping the small symbol inside a coin's box brings up the screen that holds that coin. More in jump to a coin and the remote buttons.

A coin with no price shows "-.--" where the price goes, with a short note under it that says why, and its row of figures is cleared so nothing from the screen before survives under the new name. The other coin shows its real price, because each band is judged on its own. The screen still gets its full time, and the missing coin is fetched again the next time its screen comes around.

When a card from Show Market Info is due, it takes a turn of its own between two screens, and the rotation then carries on with the screen that was next, so no pair loses its turn. At power-on the cards you have switched on come first, before the first screen of coins. After that first round, cards keep at least 30 seconds from each other and from the address card, so they never stack. See Market Info.

The address card from Show my IP address appears as a fresh screen comes up: the written address in a box in the middle of the screen, over both coins, or the QR code over the whole screen. When it has had its time, the rotation moves on to the next screen, so the screen it covered does not get a second turn that round. See the address card.

At the factory settings, Two per screen shows each coin's icon and name on its title line and the full row of figures under each price: the 24h% at the right, and on the left 24h Vol, Market Cap and Market Cap Rank taking turns, each for a third of the screen's time. Each screen stays 10 seconds. Between screens come the Market overview and Sector heat cards, a round every 10 minutes with each card up for 7 seconds, and the colors are the Default colorset's green and red. The Default settings picture above shows the volume turn.

These are the values Two per screen has until you change them. They take effect whenever Per screen: is set to Two, and One and Four per screen have factory values of their own.

The “Bare essentials” picture is the sparest screen Two per screen allows: the Title Area set to Symbol with the Icon switch off, and all four switches in the Price Area off. That removes the icon, the name and the whole row of figures from both halves, the 24h% included. Each coin keeps two things: its symbol and its price. One thing to watch: with Symbol alone, two different coins that share a symbol look identical, and the settings page warns you under the Title Area when your list has such a pair; see coins that share a symbol.

When the figures go, the freed height goes to the prices. With the row gone, a price is no longer held one size down to leave room for figures, so it can use the ticker's largest price size, 45 pixels tall against 41 with the figures on, and both halves share one height limit, which keeps the pair in step. The symbol sits alone on its title line in the largest title type that fits. With the 24h% gone, the color of each price is the only sign of which way the coin moved: up, down, or gray for a change that rounds to 0.00%.

Nothing else moves. The two bands keep their 118 pixels each and the prices stay right-aligned, so switching between the two changes what fills each band, not where the coins sit.

Every combination keeps the price, its color, and a text title. The Title Area always has one of Symbol, Name or Both selected, so Two per screen has no icon-only title; Four per screen does, where Icon is one of its two choices. What appears between screens is switched separately on the Global settings page: with both Market Info cards off, no market cards come between screens, and the address card has its own switches under Show my IP address.

Five title choices and the sixteen on-off combinations of the four figures make 80 combinations for this screen, before the colorset, the figure colors and the V/M prefix are counted. Every one of them is set on the settings page and shows on the glass at once, redrawn from the prices already on the screen, so the quickest way to choose is to change a setting and watch the ticker.

The Title Area, the four figure switches of the Price Area and the Show Two for: time belong to this layout alone. While Per screen is on Two, the two sections' headings read "for Two per screen", and One and Four per screen keep values of their own. The V/M prefix and the figure colors are kept per colorset instead, so they are shared with One per screen. The Chart Area section disappears from the page, because this layout has no chart; its settings stay as they were for One per screen. The coin list is shared by all three layouts, and everything inside the Global Settings border, such as Market Info, the address card, brightness and the colorset, applies to every layout.

Two per screen has no chart because a chart needs a band of its own and a coin's price history, and this layout has neither. A band of 118 pixels holds a title, a price and a row of figures, with no room left for a chart, and a screen of two fetches only the latest figures for both coins, not their history. For a chart, switch Per screen to One; see the chart on the One per screen page.
