Writing an alert

The condition, the message, and when it may repeat.

AlgoBarsX

alert "RSI bullish divergence"
check: every 15m
repeat: once per bar
show_on_chart: true
input rsi_length = 14
input lookback = 30
momentum_now = rsi(close, rsi_length)
lower_low = low < lowest(low, lookback)[1]
higher_rsi = momentum_now > lowest(momentum_now, lookback)[1]
when lower_low and higher_rsi and was(momentum_now < 30, within: 5 bars):
notify "Bullish RSI divergence on {market.symbol}: RSI {momentum_now:0.0}"

Setting	What it does
`check`	How often the condition is checked, such as `every 1m`.
`repeat`	`once`, `once per bar` (the default), `once per bar close` or `every time`.
`cooldown`	The shortest gap between two messages.
`expires`	When the alert stops watching.
`show_on_chart`	Marks the chart where it fired.

notify sends the message. In version 1 it is delivered in the app and in AI chat. Testing an alert shows you the messages it would have sent and the ones its own settings held back.

Alerts that watch the account, not the chart
