Live Book - diversifying over trading dates

Let’s say you run a trend following type strategy that reconstitutes and rebalances once every 4 weeks.

By having just one trading day every 4 weeks, the strategy’s results are dependent on the trading date. Perhaps the signal would have been different had the strategy traded a week before instead of today.

To diversify over trading dates, ideally, the same strategy is combined in a book four times - each with reconstitution and rebalancing every 4 weeks and with 25% of the capital - but with a different trade day within the timespan of those 4 weeks (1 week before, 2 weeks before and 3 weeks before the original system).

How would you make this happen in Portfolio123?

Do you mean on Monday, Tuesday, etc.? For a sim? If so, use WeekDay formula in the sims with daily rebalance combined with nodays>27 (every four weeks). Weekday returns the week day of the current trading day (1 = Sunday, 2 = Monday, ..., 7 = Saturday).

You can create four strategies with four different starting dates and put them in a book.
