Multi-condition alerts

Conditions share a candle

Every condition in an alert is evaluated against the same closed candle. That is what makes a compound alert stronger than two separate ones: a price alert and a volume alert firing within a few minutes of each other is not the same claim as both being true on one bar.

AND versus OR

AND requires every condition to hold. Use it to add confirmation — a level breaking and volume expanding. OR requires any one to hold. Use it to watch several exits from one setup, such as either side of a range.

The choice applies to the whole alert, not to individual rows. There is no nesting: you cannot express A AND (B OR C). In practice that shape almost always splits cleanly into two alerts, and flattening it keeps the sentence readable.

A worked example

A breakdown worth acting on, rather than every wick through a level:

close < 45,000
AND
volume > 2 x SMA(volume, 20)

Both must be true on the same 15m close. A wick below 45,000 that recovers does not fire. A close below on thin volume does not fire either.

Crossovers as conditions

crosses above and crosses below compare the current candle against the one before it, so they fire on the transition rather than on the state. Mixing one crossover with a plain comparison is a common and useful shape: fire when price crosses above its average and volume is expanding.

A crossover needs one extra candle of history, which slightly reduces how far back the service can replay if it ever falls behind.

Every condition type is free

The free tier limits how many alerts you can keep active, not what they can express. Moving averages, multipliers, crossovers and five-condition compounds are all available without paying.
