Book alerts

Book alerts watch the order book itself, not just the last price. They tell you when a wall goes up or gets pulled, when a level thins out, when the price breaks through, or when the spread widens. You set them from the Orderbook and the Ladder.

What you can watch

On one price level:

On the whole book, with no level to pick: Wall near price fires when a big level shows up within a few cents of the price, and Wide spread fires when the spread gets wider than your limit.

Alerts fire on changes. If a wall already stands when you set Wall up, the alert waits for the next one.

Using it

Where to find it

The Ladder always has the bell in its header. In the Orderbook, turn on Show in this book under Book alerts in settings, and the bell joins the toolbar. Levels with an alert get a yellow mark under the price.

   What Alt + click sets

Setting an alert

The fastest way is Alt + click on a price. It sets an alert right away with the type and template you used last, and the pop-up that confirms it has Undo in case you hit the wrong price. The first time, it opens the form instead. Alt + click never places an order, even with Click Trade on.

To pick the type yourself, open the form. In the Ladder, click a price. In either widget, click the bell, then Pick a level, then a price.

Pick the alert type, then a template. Every type has a Default, and + adds your own. Whatever you change on a new alert is saved to its template, so the next one starts the same way.

Amount is either a fixed dollar amount or one that scales with the market:

• Fixed $: the same dollar amount on every market.
• × typical: a multiple of a typical level on this market, so one template fits thin and deep books alike.
• % of level: a share of what stands on the level you click. Wall pulled and Thinned out offer this instead of × typical.

In the settings row at the bottom of the form (open it with the pencil), Must last waits until the change has held that long, so a wall that blinks in and out stays quiet. Then quiet sets how long the alert rests after it fires.

When it fires

You get a pop-up and a sound, and the level flashes. With the Orderbook or Ladder open on that market, that happens the moment the book changes. With Pro closed, the alert still lands in your alert feed, and on Telegram if you tick Also send to Telegram.

With other widgets

• The Alerts widget lists book alerts under Markets in Manage, and Add → Order book alert sets one on any market.
• Fired alerts land in the pop-up stack with the rest of your alerts.

Tips

• Resting an order behind a wall? Put Wall pulled on the wall. If it goes, nothing stands in front of your order any more, and you'll know.
• Waiting for a breakout? Put Broken on the level and stop watching the screen.
• Lots of bots on the market? Raise Must last to 3 s, so only walls that stay make a sound.

A typical level is the median size of the 20 levels nearest the best prices. Broken and Wide spread have no amount.

Quick chips

Under each group in the bell, quick chips set common alerts in one click: Wall up, Wall pulled and Broken for levels, Wall near price and Wide spread for the whole book. A level chip opens the form at the best bid; a whole-book chip sets the alert on the market straight away. The pencil next to them picks which chips show.

Alt + click

The Alt + click menu at the bottom of the bell sets what Alt + click does. Last used repeats your last level alert, Opens the form always asks first, and picking an alert type always sets that type with its last-used template.

Alert sets

Alert sets, at the top of the bell, are ready-made groups of alerts like Walls & pulls or Breakout, sized to the book in front of you. Set up a few alerts you like? Save them as your own set and add them to any market in one click.

Changing an alert

Click an alert in the bell to edit it. In the Ladder, clicking the price of a marked level works too. In the form's header you can switch the side or click the price to type a new one. Pause one alert from its row, or every alert on the market with Pause all.
