No indicators used still getting CTB backtest

I have not applied any indicators on my chart. Why am I getting backtest results after clicking on CTB in this case?

@ninjatrader If no indicator has been plotted on charts or when an indicator is plotted which is not supported by Streak, the backtest is run on any of the common price action conditions like opening range breakouts or previous day breakouts using the values of OHLCV (Open, High, Low, Close, Volume of the candlestick chart).
