Hi, I use MultiCharts which has a recalculation command to force recalculation of your studies. I trigger it for a specific study by setting a global variable from my database program. My Discressionary strategy is such that I could not use a software without this recalculation command. If I am not wrong TradeStation does not have this command. Not that I want to switch from MultiCharts, but I am curious, are their any other good softwares that do have this command. Thanks, John.
In NinjaTrader you simply press F5 to recalculate the studies in the active chart. The only drawback is that if you have tick-based studies (i.e., calculated tick by tick rather than at the end of the period), they will be null for the historical periods. In eSignal if you right click in the chart you will get a menu by which you can reload selected studies. Between the two packages, I would recommend NinjaTrader over eSignal. Best of luck.
