Concerning Blocks:

1. what does the cumulator block do?

2. can blocks be used for intra-day data, or is daily data the shortest time increment?

3. I have created blocks and saved them in the Chart folder as plot files, but cannot access them for BackScan. How do I make the blocks available for use as indicators in BackScan.?

4. If a block takes a date and bar and outputs a date and value, what is the value in relation to the bar; is it the close of the bar or some other value?

5. What are the commands for turning the pointer on and off in blocks; I sometimes see the pointer, other times not.



Thank you

It adds together all of the values run through it. You may wish to review the following:

The shortest data feed currently available for Blocks Player is daily. I do not have a timeframe on when a Real Time Data Feed might become available.

Plots and BackScan Conditions are not interchangeable. New Block Diagrams need to be created for your BackScan Conditions. You can copy groups of Blocks from the Block Diagrams of your Plots to your BackScan Conditions. You may wish to review the following:

Limit on number blocks that cna be copied at one time?

If a Block takes a Date & Bar as Input, it can normally access the Open, High, Low and Close. What is output depends entirely on the code contained in the Block.

If a Block takes a Date & Number as Input, it will also be able to accept Date & Bar Input. In this case, the value used is the Close. The output would again depend on the actual code of the Block.

The Date Pointer cannot currently be turned on and off. It can be completely removed by right-clicking on it and selecting Remove. A new Date Pointer can be added by right-clicking on the chart and selecting Add Chart Tool | Date Pointer.

If you are sometimes seeing the Date Pointer and sometimes not seeing the Date Pointer, it is probably just a matter of whether or not it is in the visible portion of the chart. If this is the case, there should be a small arrow pointing to the left in the lower left hand corner of the chart or a small arrow pointing to the right in the lower right hand corner of the chart. Single left-clicking this arrow should bring the Date Pointer into the visible portion of the chart.
