Main concept of using Price Border Indicator is that price is constantly moving from extremes showed by upper and lower bands. When price touches the lower band it means the price is in oversold zone and you should look for long trades, analogically when price touches the upper band it means the price is in overbought zone and you should look for short trades. Be cautious during periods of strong trends when price can ride one band and not bounce so quickly.
