This particular layout has condition markers in red at the bottom, the conditions include:trading with the trend in the stock, trading with the trend in the sub-industry group, stochastics and RSI in a favorable place, a small pullback against the trend before entering and a few other things. So when there is a red marker and a red candle on the same day, those tend to be the highest probability areas to enter the trade.
This is another indicator, when red the environment is more favorable for swing shorts, when light blue, more favorable for swing longs, there is still some work to be done here though to trade with the trend. The volatility stop indicator can also be used rather then the candlestick color.
