This chart style is identical to the standard NinjaTrader candlestick style except that it uses the previous candle's closing value for the current candle's open value (except when the current bar is the first bar of a session). This eliminates single tick gaps between intraday bars when the last price changes on the first tick of a new bar. As a result, charts appear smoother and are easier to read and interpret, without any price data truly being modified. See attached example of NQ.
