x- (cross under)

This is a shorthand notation we use to indicate cross under. For example A x- B means A crossed under B. A can be a technical analysis indicator (TAI) such as a simple moving average or a value. B can be another TAI or a value.

For example: SMA(50)(Closing Price) x- SMA(200)(Closing Price) means that the 50-day simple moving average of closing price crossed under the 200-day simple moving average of closing price.

Another example: Volume(Today) x- SMA(20)(Volume) which means today’s volume crossed under the 20-day simple moving average of volume.
