Screening can now be done earlier

Previously, screening could be done on the latest close date only after 7.45PM ET (8.45PM ET during daily saving). We have now added a provisional load from our data provider which means that latest day screening can now be done at 5.00PM ET.

ADX Enhancements

Posted by: Ron Garden on Wednesday, January 31, 2007 11:35 AM (UTC)

A couple of enhancements have been made to Average Directional Index (ADX) charting, screening and backtesting.

Two parameters can now be specified for ADX: one for the DI calculation and a second for the smoothing ADX calculation. Previously, both calculations used the same value.

Also, ADX / DI charts have been modified slightly in that the +DI is now plotted as blue and the -DI as red.

Horizontal line overlays can now be included on charts. Also, you can now specify a number of empty bars to provide space before the right hand y axis

Weekly Screening and Backtesting criteria now available

Posted by: Ron Garden on Sunday, October 29, 2006 8:31 AM (UTC)

Technical criteria can now be specified as either daily or weekly when creating screens and backtesting strategies. Both daily and weekly criteria can be combined in the same screen or test.

Current week

Please note that a weekly bar will be created for the current week even though it may not yet be complete.

Depth of data available

For optimal response times, our screens and backtests use up to 3 years worth of daily data. In weekly terms that is approximately 168 weeks which means that weekly technical criteria will have be within this limit.

However, for many symbols, our standard charts now include up to 7 years worth of data so you may see calculation differences between the screener and charts when using long periods if the indicator is of the type which includes an element of prior data.

For example, exponential averages, and any indicator based on them, are affected by prior data but simple moving averages are not.

Enhancements to Screening Subscription Entitlements

Posted by: Ron Garden on Monday, September 18, 2006 7:13 AM (UTC)

As well as the addition of the backtesting tool, enhancements have also been made to subscription plans with regards to which Close Dates can be accessed using the screener.

Bronze - was up to 1 week ago, now up to 3 months ago

Silver - was up to 6 months ago, now up to 1 year ago

Gold - was up to 6 months ago, now up to 2 years ago

The dates are the same as those available for backtesting and allow detailed screens to be run for any date in the backtest. This helps to clarify how stocks are being included or excluded depending on the multiple symbol rules for the strategy.
