I wanted to create a scanner where any share (F&O) crosses above (ATR Trailing Stop 21,3) on a 4-hour time frame.
The scanner has been created using the ‘Multi timeframe’ function where the base timeframe of the strategy is 1 minute and the multi-timeframe used is 4 hours. This means that after the close of every 1-minute candle, Streak will check if the entry condition is True on the 4 hours candle (partial candle).
The “Multi timeframe” function, by design, checks your conditions on partial candles, as the larger time frame candles take more time to be completed, whereas, the “Multi timeframe Completed” function checks for completely formed candles (of the same or larger timeframe).
Due to the use of partial candles, the “Multi-timeframe” function backtests have a look-ahead bias and thus the alerts can be unverifiable on the charts, whereas, the “Multi timeframe Completed” function does not consider partial candle information and does not have a look-ahead bias.
