我已经创建了可以在很短的时间内多次满足的警报条件，因此我将在 5-10 分钟内收到多次警报 - 但我更喜欢只有一个警报，并且所有警报的间隔为至少 7 分钟。换句话说，如果之前满足警报条件，脚本应该等待 7 分钟，直到再次扫描相同的条件。

我有的：

float i_seconds = input.int(420, 'Alert Delay', minval=1, tooltip='Seconds to delay alert condition.')

// ————— Function returning the duration in seconds for which `_cond` is true, per 14 bars.
f_secondsSince(_cond) =>
    // bool _cond     : condition to test.
    varip float _timeBegin = na
    varip float _lastTime = na
    varip bool _lastCond = false
    varip int _barsSince = (ta.barssince(_cond))
    if _cond
        if not _lastCond
            // First occurrence of true `_cond`; save beginnning time.
            _timeBegin := timenow
        _lastTime := _timeBegin
    else if (not _cond)
        if (_barsSince<=14)
            _timeBegin := _lastTime
    else
        _timeBegin := na
    // Remember the last state of the `_cond` so we can detect transitions.
    _lastCond := _cond
    // Return seconds since beginning of condition, or `na`.
    float _return = (timenow - _timeBegin) / 1000
    _return


// —————————— Calcs

// `true` when an alert must be triggered.
varip bool alertBull = na
varip bool alertBear = na

// Conditions of which we test the duration.
bool bullCond = before10AMBull or after10AMBull
bool bearCond = before10AMBear or after10AMBear

// Get duration of each condition, resetting the timing when user has selected to reset timing on new realtime bars.
float secondsUp = f_secondsSince(bullCond, i_reset and barstate.isnew)
float secondsDn = f_secondsSince(bearCond, i_reset and barstate.isnew)

// Trigger alerts if limit delay/duration was reached.

alertBull := (secondsUp > i_seconds)
alertBear := (secondsDn > i_seconds)

// —————————— Alerts

if bullCond and (alertBull or na(alertBull))
    alert('Support', alert.freq_all)
           
if bearCond and (alertBear or na(alertBear))
    alert('Resistance', alert.freq_all)
