Dollar-Cost-Averaging-in-Blocks

Configure Position Sizing to a Fixed Dollar size and click the "Multiple Positions" button. The strategy (whatever it is) will now buy fix dollar sizes whenever the entry conditions are true. The number of Open Positions can be controlled by the Strategy Settings.

The problem with blocks will be to create a strategy that ignores a condition once it has been triggered so that only the subsequent condition(s) can trigger new positions; a state variable could also be used for that purpose. However, these features aren't offered in blocks.
