to go about building your own private indicators。
新手在开始调参数前最好先学习一些标准的技术指标。一些交易者自己发明了指标,可以分析大众行为,确认市场波动。让我们来看看是如何自己发明指标,以及如何发明自己的指标。
All good indicators reflect some aspect of market reality。 Market Thermometer helps differentiate between sleepy; quiet periods and hot episodes when market crowds bee excited。 It can help you adapt your trading to the current environment。
优秀的指标反映了市场的真实面。市场温度可以帮助区分沉静的和激烈的市场波动。它能帮助你根据市场环境变化改变交易。
Quiet markets typically have narrow bars that tend to overlap one another。 Hot; boiling markets tend to have wide bars whose highs and lows extend far outside the previous day’s range。 Beginners jump into trades during those wide bars; afraid to miss a runaway move。 If you enter when the markets are quiet; your slippage is likely to be lower。 Hot markets are good for taking profits because then slippage may work in your favor。
平静的市场一般竹线比较短,互相重叠在一起。火爆的,激烈的市场,竹线比较长,最高点和最低点也比之前的日内波动要大。新手跳进这样的交易,害怕自己错过了波动。如果你在市场平静时进场,你的滑点亏损很低。
When gold recently ran up 40 in one week; a journalist asked a famous investor whether it was a good buy。 Gold was good; he said; but the time to get on this bus was when it stood in front of the station; and not rolling down the highway at 40 miles an hour。 Market Thermometer helps you recognize when the bus slows down in front of the station; picks up speed; or roars down the highway。
黄金最近一周涨了40元,一个记者问一个著名的投资者是否是好的买入机会。黄金不错,他说,但是最好的上车地点是车站,而不是在以40里/小时下高速公路的地方。市场温度会帮你认识公交车何时在车站减速,何时加速,或何时飙下高速公路。
Market Thermometer measures how far the most extreme point of today; either high or low; protrudes outside of yesterday’s range。 The greater the extension of today’s bar outside of yesterday’s; the higher the market temperature。 Here’s the formula of Market Thermometer:
市场温度计算今天的极限位置在哪里,最高点或最低点,是否会突破前一天的范围。今天的竹线比昨天的越长,市场温度越高。下面是市场温度的公式:
Temperature = the greater of either (Hightoday … Highyesterday) or (Lowyesterday … Lowtoday)
温度=2者取1(今天的最高价…昨天的最高价)或者(昨天的最低点…今天的最低点)
To program Market Thermometer into Windows on WallStreet software; use the following formula:
如果要把市场温度编入“华尔街”软件的窗口,用下面的公式:
if (hiref(lo;…1); 0; if ((hi … ref(hi;…1)) 》 (ref(lo;…1) … lo); hi … ref(hi;…1); ref(lo;…1) … lo))。
It is easy to adapt this formula to other software packages。
把这个公式套入其它软件是很容易的。
Market temperature is always a positive number; reflecting the absolute value of either the upward or the downward extension of yesterday’s range; whichever is greater。 Plot temperature as a histogram above zero。 Calculate a moving average of market temperature; and plot it as a line on the same chart。 I use a 22…day EMA because there are 22 trading days in a month; but feel free to experiment with shorter EMA values if you want to make this indicator more sensitive to short…term swings。
市场温度永远是正数,反映了上涨或下跌幅度跟前一天相比的绝对值,看看哪个大。可以把温度画成0轴上的柱状图。计算市场温度的平均值,然后用同样的图画成线。我用22日均线,因为一个月有22个交易日。如果你想做短线,你也可以自己测试数据,用更小的参数。
When markets are quiet; the adjacent bars tend to overlap。 The consensus of value is well established; and the crowd does little buying or selling outside of yesterday’s range。 When highs and lows exceed their previous day’s values; they do so only by small margins。 Market Thermometer falls and its EMA slants down; indicating a sleepy market。
当市场平静时,相邻的竹线都重叠了。对价值的一致认同被确定了,市场的买卖很少,没有超过昨天的波动范围。当最高点和最低点超过了前一天的数值,他们只是轻仓交易。市场温度下跌,均线下跌,表明市场平静。
When a market begins to run; either up or down; its daily bars start pushing outside of the previous ranges。 The histogram of Market Thermometer grows taller and crosses above its EMA; which soon turns up; confirming the new trend。
当市场开始波动,上涨或下跌,日线图竹线开始突破前一天的范围。市场温度涨的比均线高,很快上涨,确认了新趋势。
Market Thermometer gives four trading signals; based on the relationship between its histogram and its moving average:
市场温度根据柱状图和均线的关系给出4个交易信号:
The best time to enter new positions is when Market Thermometer falls below its moving average。 When Market Thermometer falls below its EMA; it indicates that the market is quiet。 If your system flashes an entry signal; try to enter when the market is cooler than usual。 When Market Thermometer rises above its moving average; it warns that the market is hot and slippage more likely。
当市场温度下跌到均线以下时是最好的建仓点。当市场温度跌到均线以下,它表明市场很平静。如果你的系统发出进场信号,可以在市场比平时还平静的时候进场。当市场温度涨的比均线高,它警告说市场很火了,容易导致滑点亏损。
Exit positions when Market Thermometer rises to triple the height of its moving average。 A spike of Market Thermometer indicates a runaway move。 When the crowd feels jarred by a sudden piece of news and surges; it is a good time to take profits。 Panics tend to be short…lived; offering a brief opportunity to cash in。 If the EMA of Market Thermometer stands at 5 cents; but the Thermometer itself shoots up to 15 cents; take profits。 Test these values for the market you are trading。
当市场温度涨到均线的3倍时,平仓。市场温度指针表明要逃跑了。当市场突然受到新闻和波动的冲击,此时最好兑现利润。恐慌一般是短期的,提供了兑现利润的机会。如果市场温度的均线站在5分,但市场温度涨到了15分,兑现利润。你要在你的市场测试数值。
Figure 6。7 Market Thermometer
图6。7 市场温度
Nvidia Corp (NVDA) is one of the current favorites among active traders。 Just look at its many tradable features … a powerful rally to 100; its triple top; a MACD bearish divergence; and a subsequent downtrend。 Markets oscillate between quiet and active periods; and the Thermometer helps you identify them。
内维蒂雅公司股票是活跃交易者喜欢的市场之一。看看它的很多特征——强势涨到100,形成三顶,MACD看跌背离,接着就下跌。市场在平静和活跃之间振荡,温度帮助你确认它们。
At point A; the stock is in an uptrend; while the Thermometer has been below its 22…day EMA for five days。 This is a quiet before the storm。 An explosive move in the direction of the trend (point B) rewards buyers。 At the same time a very high Thermometer reading; three times above the average; warns that the fun and games are over; the move is exhausted; and it is time to take profits。 At point C the Thermometer shrinks again; spending five days below its EMA and warning that a sharp move is ing。 Since prices are above their EMA; expect a decline。 A similar message emerges at point D。 After the next rally (point E); an extremely high reading of the Thermometer; more than four times the average; warns that it is a good time to take short…term profits。 Prices make a triple top near 100; MACD…Histogram traces a severe bearish divergence; and at points F and G prices hang flat。 This is another quiet before the storm as bears swing the stock down。
在A点,股票在上涨趋势,温度已经在均线之下5天了。这是暴风雨之前的安静。在B点的爆炸式上涨回报了买家。同时温度值很高,比均线值高3倍,警告说游戏的乐趣结束了,波动竭尽了,此时最好兑现利润。在C点温度又下跌了,在均线之下5天,警告说剧烈的波动来临。因为价格在均线之上,期望会下跌。在D点发出了类似的信息。第二次上涨之后(E点),温度值特别高,是均线的4倍多,警告说此时最好兑现短期利润。价格在100左右形成三顶,MACD柱跟踪到了严重的看跌背离,F点和G点都有提示。这是在下跌前又一次暴风雨之前的安静。
The EMA of the Thermometer tells you how far today’s high or low is likely to be above or below yesterday’s extreme。 This is a useful piece of intelligence for those who like to buy low or sell high; you can place your order for the day near the projected extreme。
温度的均线告诉你和前一天比,今天的最高点和最低点可能在哪里。对喜欢低买高卖的人来说,这是有用的信息。你可以在可能的极限位置下单。
At the right edge of the chart; prices have just shot up to their d
