CS5402

error Stopped: one live update took too long (ms ms; the limit is max ms).

#What it means

One live update of the current bar took longer than allowed (the message gives the time and the limit). Live updates must be quick so the chart keeps up with the market, so the script was stopped.

#Typical cause

• Heavy work that runs on the live bar, such as large loops or sorts guarded by barstate.isrealtime or barstate.islast.

#How to fix it

Move the heavy work out of the live bar, do it only when a bar closes (barstate.isconfirmed), or make it smaller. See Performance.

#Example

//@chartscript 1
indicator("Live heavy")
let total: float = 0.0
if (barstate.isrealtime) {
    for (let k = 0; k <= 7; k++) {
        const xs = array.new_float(0)
        for (let i = 0; i <= 99999; i++) {
            xs.push(math.sin(i * close))
        }
        xs.sort()
        total += xs.get(0)
    }
}
plot(total)

Fixed

//@chartscript 1
indicator("Live light")
let total: float = 0.0
if (barstate.isrealtime) {
    const xs = array.new_float(0)
    for (let i = 0; i <= 999; i++) {
        xs.push(math.sin(i * close))
    }
    xs.sort()
    total += xs.get(0)
}
plot(total)
