Price could shows you dynamic support resistance levels. It also displays two bands (ie clouds) that show you where the trend is. If the price hits the bottom of the high band thats a buy and if it hits the top of the high band its a sell. During times of volatility the price can break support but you will find that the opposite band will work as the next level. I added tool tips for every option to help explain what everything does and I also left suggestions for other settings.
This works great on everything! That being said I have this setup in a general way that works really well for 20m forex. If you are scalping you might want to speed up the indicator. This is also true if you want go to the daily chart or above. Adjust the Stdev to match the market.. and I mean really play around with.. dont be shy! With all that out of the way this really will work out of the box. If you like this indicator its actually the same thing as my (PBS) but this one is an overlay on the chart. (Also as of publishing this script the code for this version is way cleaner. In fact I plan on replacing PBS with this as its base)
