Ok, I tried, but nothing changed – see attachment below. The previous High/Low are still wrong.

Sure, previous OHLC values have to be calculated! BUT due to several other settings this is difficult for the USER. This makes it time consuming for the USER!!! With the variable Dhigh/Dlow everything works fine!!!! So users also need further variables for Hour/Month/Week etc. High/Low (even better OHLC). In this Forum so many users have problems with this!!! Just an example below out of TradingView. Within one line of code I can adress every OHLC within every previous hour/day/week/month and I can plot his information in every chart with every timeframe. If I change the exchange hours in TradingView, the calculation simply adapts the OHLC to the new exchange hours – VERY SIMPLE. Also easy possible in other charting software….

To put it simple: Like Dhigh and Dlow, which exist now in PRT, further varibales are needed.

//Monthly
mo = security(tickerid, ‘M’, open[1], lookahead=barmerge.lookahead_on)
mc = security(tickerid, ‘M’, close[1], lookahead=barmerge.lookahead_on)
mh = security(tickerid, ‘M’, high[1], lookahead=barmerge.lookahead_on)
ml = security(tickerid, ‘M’, low[1], lookahead=barmerge.lookahead_on)
//Weekly
wo = security(tickerid, ‘W’, open[1], lookahead=barmerge.lookahead_on)
wc = security(tickerid, ‘W’, close[1], lookahead=barmerge.lookahead_on)
wh = security(tickerid, ‘W’, high[1], lookahead=barmerge.lookahead_on)
wl = security(tickerid, ‘W’, low[1], lookahead=barmerge.lookahead_on)
//Daily
do = security(tickerid, ‘D’, open[1], lookahead=barmerge.lookahead_on)
dc = security(tickerid, ‘D’, close[1], lookahead=barmerge.lookahead_on)
dh = security(tickerid, ‘D’, high[1], lookahead=barmerge.lookahead_on)
dl = security(tickerid, ‘D’, low[1], lookahead=barmerge.lookahead_on)
//1 Hour
oho = security(tickerid, ’60’, open[1], lookahead=barmerge.lookahead_on)
ohc = security(tickerid, ’60’, close[1], lookahead=barmerge.lookahead_on)
ohh = security(tickerid, ’60’, high[1], lookahead=barmerge.lookahead_on)
ohl = security(tickerid, ’60’, low[1], lookahead=barmerge.lookahead_on)
