pending

The pending function is used to obtain the number of concurrent threads running in the current strategy program.

The pending() function returns the number of concurrent threads that the current strategy program is running.

pending()

function threadFun1() {
    Log("threadFun1")
    Sleep(3000)
}

function threadFun2() {
    for (var i = 0; i < 3; i++) {
        LogStatus(_D(), "print from threadFun2")
        Sleep(3000)
    }
}

function main() {
    Log(`begin -- threading.pending():`, threading.pending())

    var t1 = threading.Thread(threadFun1)
    var t2 = threading.Thread(threadFun2)
    Log(`after threading.Thread -- threading.pending():`, threading.pending())

    t1.join()
    t2.join()
    Log(`after thread.join -- threading.pending():`, threading.pending())
}

Create two concurrently running threads and call the pending() function at different time nodes.

When the strategy main() function starts running, calling the function pending() directly will return 1, because the main thread where the strategy main() function is located is also a pending thread.

It supports backtesting system and live trading environment.
