An example of binary option arrows for candlestick patterns bearish and bullish harami. With results as colored background and an option to choose your expiration (one candle by default). It's just an example for those who has their own strategy and wants to make nice arrows in their chart. All you need to do is rewrite piece of script in lines 9:13 - feel free to ask me for any help, but I believe it's all clear.
Disclaimer: It's just an example how to script arrows for binary option and I am not responsible for any loss of money by using this particular strategy.
I wish happy and successful trading! ;)
