%%All of them do; a five hour chart requires 5 hours.And smaller the time frame, more the errors.End of day helps.Except for NYSE ,open price can vary more...............................................................................................................
On non NYSE charts, open price on 2or 3 different [brand]charts, maybe 2,or 3 different numbers.In a bull market, which we are not in, i may record higher number, open price. In a bear market, i usually record the lower number , on open price, regular market hours.
I appreciate your feed back...but i dont think we look at the market the same way. Anyways best of luck
