PrescienTrader allows you to overlay two higher time period plots onto the base period chart. Additionally, when using the analysis functions to create an exploration, backtest or optimization, you can analyze an unlimited number of higher time periods. Higher time period analysis can be extremely useful in creating a broader context for the base period indicators. For example, you could use a higher time period to filter base period signals that conflict with the higher time period signals.

When you plot a higher time period overlay, AmiBroker expands the higher time period bar over an equivalent number of bars on the base period chart. Due to various factors, the expanded data series may not exactly match the data series on the higher time period chart. This could cause minor discrepancies when you compare the values calculated by PrescienTrader from the higher time period chart vs the values calculated from the equivalent higher time period overlay on the base period chart. This is nothing to be concerned about as the differences are usually slight and shouldn’t affect your trading signals significantly.

Additionally, when you use the Projection Bars parameter to plot the Prescient Line into the future, this offsets the entire array by the specified number of projection bars. This offsetting can cause the higher time period overlays to get out-of-sync with past dates. For example, on a monthly overlay, you may notice the plot for a given month begins on the third or fourth day of the month, instead of the first day. Again, this is not a major issue, as it only affects the chart display, not the backtesting, exploration or optimization results. However, if you want to ensure the values from your chart display match the values returned when using these analysis features, you should set Projection Bars to zero in the chart display Parameter Settings.
