FAQ
How does Bias Drill grade a candle?
Bias Drill grades a candle by measuring how far it expanded above and below its open. If one side is at least 1.5x, 2x, or 2.5x the other (user-selectable), that direction is considered the expansion. The close is ignored for grading purposes.
What markets can I practice on with Bias Drill?
You can practice on five simulated markets (Nasdaq-100 futures, S&P 500 futures, Bitcoin, an S&P 500 ETF, and a random character) and two real history markets (EUR/USD weekly since 1999 and WTI crude oil weekly since 1986). You can also import up to 8 CSV files of your own data.
