Why a level alert can show a price on the other side of the line
A level alert fires when the price has gone past a line you set. The last price on that alert can still sit on the other side of the line. The check uses the high or the low of the minutes since the last look. The last price is the price at the moment of the look.
It does not tell you what to do with a coin.
What the check looks at
A level is not watched on every trade. How often alerts are checked names the schedule and the oldest price a plan will use. Between two looks, the price can touch your line and move away.
For a line above the price, the check takes the latest price and the high of each 1-minute candle in a short window. It fires when the highest of those prints is at or past your level. For a line below, it uses the lows, and it fires when the lowest print is at or past your level. Landing on the level counts.
The window starts at the latest of four clocks.
- The start of the minute that held the previous check.
- The first minute boundary at or after the alert was created, edited, or turned on.
- The first minute boundary at or after the alert armed again.
- The first minute boundary at or after its wait ended.
A minute that started before one of those clocks is left out, at this check and at every later check. Its high or low might come from a time when the alert was not watching. The latest price still counts, even when no candle in the window does.
A touch between two checks fires at the next check. A print from before the alert was watching does not. Where prices come from says how the candles are built. A missing minute is a gap. It is not written as zero.
The price on the alert, and the price that crossed
The alert stores the latest price at the check, the exchange it came from, and the time of that price. That is the last-price line. When the crossing was a candle high or a candle low, that last price can already be back on the other side of your line. The headline still says the price went past the level. The last-price line shows where it is now.
Say the level is $100. This is an example, not a live price. One minute in the window prints a high of $101. At the check, the latest price is $99. The alert fires. The last-price line shows $99. A second line says it reached $101, and it names the exchange and the minute of that high.
That second line appears only when the extreme is at or past the level and the last price is not. If the last trade was the extreme, or the exchange or the minute is missing, the line is left off.
The Today list, the alert page, email, and Discord show the longer line when the message has room. The phone notification does not. Its short line names the level and the minute of the high or the low. When that minute is missing, it uses the time of the last price.
What is stored with the alert
A level above stores the level you set, the price where the alert can arm again, the high, the minute of that high, the exchange of that candle, and the first minute of the window. A level below stores the low in those same places. The minute and the exchange are empty when the latest price was the extreme. Alerts and rules names the level types. The later receipt is a different record.
After the alert fires, it is no longer armed. It arms again when the latest price moves back through the band the builder shows. It fires again only after the wait has ended. It does not arm and fire in the same check. A price that stays past the level fires once. A crossing during the wait fires at the end of the wait only if the price is still past the level. The window then starts from the minute the wait ended. Quiet hours do not erase the fire. A level that is still true when they end can be sent once.
What this does not mean
The high or the low says where the line was met. The last price says where the market was at the check. The alert does not grade the level. A cross can be followed by a price that goes anywhere. The later prices, at 1 hour, 4 hours, 24 hours, and 7 days, are a receipt. How to read a crypto alert receipt explains those slots. They are not part of the crossing check.
If the price at the check is too old for the plan, the check skips the coin. An old price does not fire, and a missing price says unavailable.
Terminal stores the high or the low that met your level, the minute it printed, and the exchange it came from, and it still shows the price at the check when that price has moved back across the line.
FAQ
Why is the last price on the other side of my level?
The check uses the high or the low since the last look, not only the price at the look. In the $100 example above, a minute can print $101 while the price at the check is $99. The last-price line is the $99. The extra line names the $101, the exchange, and the minute.
Which minutes are allowed to count?
Only minutes that started at or after the previous check, and at or after the alert was turned on, armed again, or finished its wait. An earlier minute is dropped whole. Its high or low might be from before the alert was watching. The latest price still counts on its own.
Does the phone notification include the longer line?
No. The phone notification names the level and the minute of the cross, in a short line. The Today list, the alert page, email, and Discord carry the longer line when the extreme is past the level, the last price is not, and the exchange and the minute are both stored.
