Please help!

-If this is in the wrong section I apologize!
I am a new trader and I am trying to buy and sell small amounts in short amounts of time..I am trying to configure my chart with the pivot reversal strategy and the SMI oscillator. It seems like the default values (especially for the PRS) do not give good indication of when to buy and when to sell. The red indicating to sell are usually lower than the blue arrows indicating when to buy. Also the little ticker at the top always shows the sell price being lower than the buy price...so I am trying to figure out what input values I can put in so that I can sell high and buy low...thank you all so much!
