I don't fully understand the question but for short term trading you can use the Stochastic signals to buy and sell. Buy at the green arrow where the light blue line crosses the dotted line to the to the upper side, sell at the gun where the light blue ine to get crosses to the other way around.
RSI seems to go in the same direction with the Stochastic signals.
I wonder if you can generate the Bollinger Bands from the chart.
I just read chart for stock trading so I do not know how much these short up & down movements would bring money to the traders after the commission but to me the reading is very straight forward.
Cheers,
