These indicators may be "cumulative" indicators. A cumulative indicator is one that builds upon itself (using its own previous value). For example, any indicator involving an exponential smoothing fits into this "cumulative" category. When an indicator is cumulative, its value is dependent in some way on all previous data elements that are considered in the calculation. While the chart is loading a certain number of bars (depending on the chart's viewing period), the custom column is loading a minimal number of bars for efficiency reasons.

I suspect that these indicators may be "cumulative" indicators. A cumulative indicator us one that builds upon itself (it's own previous value). Any indicator involving an exponential smoothing fits into this "cumulative" category.. When an indicator is cumulative, its value is dependant in some respect on all previous data elements that are considered/loaded for the calculation. While the chart is loading a certain number of bars (depending on the charts viewing period), the custom column is loading a minimal number of bars for efficiency purposes.
