标准差倒卖法 (Standard Deviation Scalping Method)

Hi,

I found a Scalping technique called "5-min Standard Deviation Scalp" (pattern #5 in the document enclosed). I would like to know if anybody has tried this technique.

Briefly, on a 5 min chart, you apply a 10 bar moving average and bands 1 std dev on each side. I am using Bollinger Band (10,1).

When the trend is up (slope of the bands), wait for price to dip inside the lower band and then enter long. Exit when price reaches the other band.

When the trend is down, wait for the price to touch the upper band and then enter short. Exit when price reaches the other band.

To make sure the direction of the trend is right when price touches the bands, I use 10EMA close and 10EMA open. If 10EMA close is over 10EMA open, the trend is up when price crosses the lower band. Reverse for down trend.

Sometimes price doesn't reach the other band, but crosses the middle line of the BB. The middle line can also become the exit signal. There are also false signals (fewer than good ones) and I'm not sure about the stop loss. I would think 1XATR can be a good guess since it's all based on volatility.

On the picture, I circled the entry signals. Sometimes price reaches the other band, but sometimes it doesn't, but most of the times it crosses the middle line of the BB.

Comments would be highly appreciated. If you can watch 3 or 4 low spread pairs, the result should be interesting at the end of the day.

Thanks.
