CTB on line chart type

In the line chart type on HDFC bank I performed the CTB, but he backtesting was shown in candlestick chart type. Why?

Hi @trader_geek line charts is plotted based on the closing price in a particular timeframe and candlestick is plotted based on the OHLC data in a particular time frame and takes close price also into account. In Streak we support candlestick chart type, which include all the price information line charts provide and create strategies based on that.
