Screw trying to figure out your own STOCH settings at this point...set several STOCH settings up and WATCH them during market action for several weeks. You are new and you do not have the background yet to be designing STOCH settings...learn about their actions first through observations and study. Much of trading is BEHAVIOR, yours and your indicators, so take the time to try different STOCH settings to study their behavior under different market conditions. See how they react in a major trend, see how they act during oscillating price action, and see how they act during tight chop. The BEHAVIOR recognition is the key for your indicators...

BTW, I suggested watching a setting at 5,5,2...see what you can observe...you might like it!
