I have added a new candlestick indicator: Inside Bar.
It doesn't fit the general inside bar definition, because I've made some interpretation based on my observations. If "IB" text appears below a candle, it signals upward move; if "IB" text is above the bar, it signals downward move.
I recommend you to backtest before counting on any indicator, and take multiple indicators into consideration at the same time to build up stronger strategies.
