Schedule Jobs

• scheduleJob: create a scheduled job.

Schedule to run a function:

def f():1+2;
scheduleJob(`daily, "Daily Job", f, 17:23m, 2018.01.01, 2018.12.31, 'D');
//output
daily

scheduleJob(`weekly, "Weekly Job", f, 17:30m, 2018.01.01, 2018.12.31, 'W', 2);
//output
weekly

Schedule to run a script:

scheduleJob(`monthly, "Monthly Job", run{"C:\DolphinDB\script\monthlyJob.dos"}, 17:23m, 2018.01.01, 2018.12.31, 'M', 1);
//output
monthly

Here we use a partial application run{<script>} as this parameter needs to be a function with no arguments.

getJobMessage(`daily);
//output
2018-02-08 17:23:27.166296 Start the job [daily]: Daily Job 1
2018-02-08 17:23:27.167303 The job is done.

getJobReturn(`daily);
//output
3

We can schedule to run the same job multiple times a day:

scheduleJob(`Trading, "Generate Trading Tickets", run{"C:\DolphinDB\script\TradingTickets.dos"}, [09:25m, 12:00m, 02:00m, 15:50m], 2018.01.01, 2018.12.31, 'D');
//output
Trading

In this case, each time this scheduled job is executed, the job ID is different. The job IDs for the first day is "Trading", "Trading000", "Trading001", "Trading002" for the first day, and "Trading003", "Trading004", "Trading005", "Trading006" for the second day, etc.

We can schedule to run the same job multiple times a day for the working days in a week:

scheduleJob(`PnL, "Calculate Profit & Loss", run{"C:\DolphinDB\script\PnL.dos"}, [12:00m, 02:00m, 14:50m], 2018.01.01, 2018.12.31, 'W', [2,3,4,5,6]);
//output
PnL

• getScheduledJobs : create a table of scheduled jobs.

getScheduledJobs();

• deleteScheduledJob : delete a scheduled job.

deleteScheduledJob(`monthly)
deleteScheduledJob(`weekly)
deleteScheduledJob(`daily);

getScheduledJobs();
