If a long term trend (weekly) is bearish, medium trend (daily) is bullish and short term trend is bearish (hourly or 15minutes interval) and you trade on the short term. Do you enter a position short or long?
You trade whatever TF you're trading with expectations of diminished performance (but marginally still tradable) if you're against the longer term bias.
You go short in general except when you think that there will be a reversal of the short term trend to align with the medium trend. What you described is in general one of the toughest problems in multi-timeframe trading.
