These filters compare the current price to the prices of the previous 5, 15, 30, and 60 minute ranges.
Time is accurate to the minute. It's like we're always looking at one minute candles, and we're looking at the last 5, 15, 30 or 60 of them. We don't just look at just one candle on different timeframes. These filters include pre and post market data.
The filter is expressed as a percentage where 100% means that the stock is trading at the highest price of the time range. 0% means the stock is currently trading at the lowest price in the time range.  50% means that the last price is exactly in the middle of the previous time period’s range.
