30minute candles since open

[Antares66]

Hello,
i´m searching for a formula to see if any of the 30minute candles since open has a percent change more than 5%.
I know i could use the "with x bars" syntax but i have to adjust the bar number every 30 minute.
At the open it´s 1 bar, after one hour 2 bars .... I search for an easier way, if possible. Could someone help?
Thanks

I want to compare each candle with the candle before. For example, has the 30 minute candle between 11pm and 11.30pm increased 5% compared to the candle between 10.30pm and 11.00 pm? The scanner should inform me if any stock matched this creteria between open and close of the market.

you didn't specify price levels,
which way?
1. from prev close to current close?
2. from prev low to current high?
3. or,...

if close is used, it will trigger as long as close stays above a certain price, but not if close drops.
if high/low are used, once a high enough level is reached, high will stay high for the remainder of the candle, causing multiple triggers, till the end of the candle.

maybe high low, or prev close / high
