Hi @attalis, The arrows represent the signal of the Stochastics crossing up or down when in the same direction as the longer-term sentiment. So in this case signal as turned up while longer-term sentiment has shows a bullish bias. I dont show the longer-term as it is something I provide for people who pay me for the tutorial.. But I do put it on my analysis of where the sentiment is from time to time. When both are in SYNC the probability is stronger and low risk. Also if the signal falls above the 80 or below the 20, this is called OB/OS. These conditions also increases probability of the acceleration in price in the direction of sentiment and signal. I should be more consistent with the arrows, but I do skip marking them from time to time. I will make sure to update it daily, Hope this helps.
