Is it safe to use OnTimer like this?

protected override void OnStart()
        {

        Timer.Start(TimeSpan.FromMilliseconds(1));
            
        }

protected override void OnTick()
        {
	    Timer.Stop();

	//Do some calculations

            Timer.Start(TimeSpan.FromMilliseconds(1));
        }

protected override void OnTimer()
        {
          OnTick();
        }

protected override void OnStop()
        {
            Timer.Stop();
        }

Would the code above work without risk causing cAlgo to crash?

Timer is from cAlgo.API.

Appreciate any and all input.
