Sam, TROHalfHourlyBuyZone is not compiling. Compilation error says "NinjaTrader.Indicator.CurrentHalfHourlyOHL' does not contain a definition for 'HalfHourBreak'. Lolu

HalfHourBreak is defined in CurrentHalfHourOHL.cs, you need to copy the two files attached.

independent of time and space, it is only the price ...

have made some changes in my insidebarv2 indicator ...

has a new feature thanx to sam for input ... is very similar to tro version

also my indicator based on inside bar and outside bar.

outsidebar - blue/ red
insidebar - gray

buy zone now is the black hash in the direction of the trend or tro's style up/down only.
i think is nice to scalping or trading and find good entries

will use limit orders on the black line, perhaps stopp orders ... as you want

best regards wh

For the record, the ORIGINAL Buy Zone is based on the session or market open. Later we tested statistics and found we could trade it on the hourly candles. I do not know about the 30 minute candles.
