The tweezer candlesticks
Time between is not written in stone , but just from expierience I would say 1 to 5 days. Remember that the candles are best used to visulize the battles (short term) within the war (long term).
tweezer formations just show where the battle lines have been drawn , whether it be supply or demand.
Tweezers also do not have to be two wicks on a candle formation.
You can get a tweezer pattern with a long white candle that closes at the top , then the next day the market opens lower moves back to the previous top finds supply and eventually prints
a bearish harami. A harami (as example), printed with a tweezer top , reenforces the reliability of the tweezer.
Basically a tweezer is just showing the same place the market finds the top or the bottom within a short term time frame.
I don't know of a site that would show this , I would suggest though both books that Steve has put together Candlestick Charting techniques , and Beyond Candlesticks. if one wanted to
delve into the art of candlestick charting.
Hope this helps
