Higher timeframe bias costs time but filters bad trades

[Amanhasnoname]

Checking the five-minute or fifteen-minute trend before taking a one-minute signal adds a step and removes many counter-trend trades. The filter often improves the win rate and reduces the number of trades.

The cost is delay. Waiting for alignment means missing some early entries, and the trade count drops. For high-frequency approaches, that matters.

The right timeframe ratio is debatable. A factor of five to fifteen between the trigger and the filter is common. Using something much larger can lag too much.

Defining bias objectively avoids hindsight. A simple rule, like price above or below a moving average on the higher timeframe, is better than a subjective read.

Testing with and without the filter shows its effect on expectancy. In some cases, fewer trades with a higher edge beats more trades with a lower one, after costs.

Writing the bias rule as one sentence before the session starts keeps it from drifting into a subjective guess.

Is a higher timeframe filter used, and what is the ratio between the trigger and the filter charts?
