Accessing 1-min indicator from a Tick cBot

private RelativeStrengthIndex _rsi;

protected override void OnStart()
{
    var rsiBars = MarketData.GetBars(TimeFrame.Minute);
    _rsi = Indicators.RelativeStrengthIndex(rsiBars.ClosePrices, 14);
}

Say I am using this cBot on a 1-Tick chart, is this the way to have an RSI on a 1-minute time frame and do I access it from the OnBar using _rsi.Result.LastValue?

Also, I am assuming the indicator will stay updated with the latest values without me having to write extra code.

Just confirming...
