Webhook trading is available. To understand how it works, use APITester.com33112 as given here. You can even test in the paper trading version of API bridge at any time of day https://mycoder.pro/apibridge/tradingview/webhook-setup/30131
However, note that webhook trading required data to be sent in a given format. I am not sure which formats are supported by ChartInk. Suggest you test APIBridge and get in touch with ChartInk team if you face any issue.
