Boomerang Effect

Based on the market behaviour that:-

"prices tend to return"

"Same Seiden's Supply and Demand concept",

"Banks always split their orders hence price tend to go back so banks can put their orders again"

hence the concept "Boomerang Effect".

Some traders mark big candles as a "leading indicator" that price tends to return to that price, think of a magnetic effect. I personally use a candle that closes above/below the Bollinger Bands (20, std dev 2.0). When a candle closes above/below, I mark that specific candle's Open Price (almost copying the Sam Seiden's method marking the Supply/Demand level).

The chart above is just an example. If you just scan around the charts to the major pairs, it does occur so many times (the boomerang effect). Does it happen 100% of the time? Of course not! Reason? Banks never split their orders all the time. The price fluctuates because it is moved by people, it is real, it is a living thing the market. There are times when they just do not want to buy again at the same price especially if it is deemed too expensive.

Tell me what you think? What kind of strategy you can incoporate this.
