Psychological Line (PSY)

Type

Momentum ratio of rising periods over total periods

How does it work?

PSY, as an indicator, is the ratio of the number of rising periods over the total number of periods. It reflects the buying power in relation to the selling power.

If PSY is above 50%, it indicates that buyers are in control. Likewise, if it is below 50%, it indicates the sellers are in control. If the PSY moves along the 50% area, it indicates balance between the buyers and sellers and therefore there is no direction movement for the market.

Trading Signals

You may also look for a divergence signal. When the stock prices make a new high (low) while PSY does not make a new high (low), it signals the divergence. You should take caution when you trade.
