Different timeframes have different characteristics. On a monthly chart you may have a doji candle which means price was the same for open and close of the candle. But during that 1 month, how much movement did we have on hourly chart? A LOT, many ups and downs. Filtering trades based on other timeframes can be good as long as these timeframes are closed to each other like H1 and H4, not MN1 and H1 which are very different. You can find a good entry on lower timeframe and filter it based on higher timeframe for pinpointing a better entry point.
