You can use the daily eod data in prt and the standard pivots to get most the levels I use but if the prev days gap does not close they will be different because the traded hi or low will the be prev day close depending if it gaps up or down. I am a quant trader, mechanical engineer with some programming language background so made my own indicator to get the levels I need from my brokers on Mt4 and Mt5. If you want you can to learn PRT custom indicators of pay someone $100 to build one all it is the HLC from 10am to 4pm and the close is the close of the 5min bar or the closing price at 4:10 after the auction.
The advantage of using your own broker data means you can change feeds and look at different feeds and not worry if they are 1-10 pips higher or lower. There are free pivot sites you can check for cash data levels but will not be filtered for false high and lows. That is where the edge is and extra work required.
