Linear Regression Slope. Should return the same values as the standard LinRegSlope. However, the standard version iterates on every update, making it especially inefficient for intrabar (tick) data. This version does not iterate on intrabar updates. Version 1.0.
Should return the same values as the standard 'SUM', hopefully with less memory overhead. Intended to be used as a component in more complex indicators. Version 1.0.
