继五月份的Box后,最近SPX又形成了一个小Box,令我想起了以前读到的Nicolas Darvas的Box Trading方法,描术如下:
"Nicolas Darvas was a successful professional dancer who also made millions in the stock market in the 50s using a charting method he described in his classic book How I Made $2,000,000 in the Stock Market. His basic approach (not including the stock selection process) is essentially a breakout technique.
Darvas defined consolidations as "boxes" and traded upside breakouts of these boxes. A Darvas Box is formed when both the box top and box bottom have been established, as follows:
1. When a stock fails to make a new high for three days, the most recent high that is higher than the three subsequent highs becomes the box top.
2. If price breaks out of the box top, repeat step 1.
3. When a stock fails to make new lows after three days, the most recent low that is lower than the three subsequent lows becomes the box bottom.
4. The box is broken when today's high price breaks out above the box top or below the box bottom.
Trade rules:
1. Go long when the price exceeds the top of the Darvas Box.
2. Sell when the price of the stock falls below the bottom of the Darvas Box." |
