我使用ta-lib进行烛台的模式识别,但是,我根据我使用过的模式函数得到了不同的数字。这些数字代表什么参考?
答案 0 :(得分:1)
TA-Lib的库返回-100 .. + 100个值。包装器什么都没改变。 解释可能在不同的函数中有所不同,但一般来说:值== 0为假,值!= 0为真。标志可能代表方向 对于CDLHANGINGMAN,其C代码为here。
根据描述:
/* Proceed with the calculation for the requested range.
* Must have:
* - small real body
* - long lower shadow
* - no, or very short, upper shadow
* - body above or near the highs of the previous candle
* The meaning of "short", "long" and "near the highs" is specified with TA_SetCandleSettings;
* outInteger is negative (-1 to -100): hanging man is always bearish;
* the user should consider that a hanging man must appear in an uptrend, while this function does not consider it
*/
虽然我觉得它很不正确,因为CDLHANGINGMAN只返回-100或0。
if( TA_REALBODY(i) < TA_CANDLEAVERAGE( BodyShort, BodyPeriodTotal, i ) && // small rb
TA_LOWERSHADOW(i) > TA_CANDLEAVERAGE( ShadowLong, ShadowLongPeriodTotal, i ) && // long lower shadow
TA_UPPERSHADOW(i) < TA_CANDLEAVERAGE( ShadowVeryShort, ShadowVeryShortPeriodTotal, i ) && // very short upper shadow
min( inClose[i], inOpen[i] ) >= inHigh[i-1] - TA_CANDLEAVERAGE( Near, NearPeriodTotal, i-1 ) // rb near the prior candle's highs
)
outInteger[outIdx++] = -100;
else
outInteger[outIdx++] = 0;
根本无法从此功能获得+100。
我还没有看到任何完整的参考资料。最好先了解一下TA-func代码。蜡烛功能&#39;代码很简单。
答案 1 :(得分:1)
-200 / -100 / 0 / +100 / +200
+200 带有确认的看涨形态
+100 看涨形态(大多数情况)
0 无
-100 看跌形态
-200 带有确认的看跌形态
例如
如果有CDLHIKKAKE模式检测功能:
正如您在源代码中看到的那样:
https://sourceforge.net/p/ta-lib/code/HEAD/tree/trunk/ta-lib/c/src/ta_func/ta_CDLHIKKAKE.c#l240
您可以再获得-100或+100(即为-200 / + 200):
如果您的模式已经确认。
因此计算将为(模式+确认)
这样,
您可能会在某些天检测到看跌模式,再过一天可以确认该模式。最后得到-200
答案 2 :(得分:0)
根据discussion:
-100表示看跌的三星图案,其中中间的蜡烛体高于另外两个。相反,+ 100表示看涨的三星模式,其中中间体位于相邻的下方。
该页面显示了一些示例和相关的源代码。
/* Proceed with the calculation for the requested range.
* Must have:
* - 3 consecutive doji days
* - the second doji is a star
* The meaning of "doji" is specified with TA_SetCandleSettings
* outInteger is positive (1 to 100) when bullish or negative (-1 to -100) when bearish
*/
i = startIdx;
outIdx = 0;
do
{
if( TA_REALBODY(i-2) <= TA_CANDLEAVERAGE( BodyDoji, BodyPeriodTotal, i-2 ) && // 1st: doji
TA_REALBODY(i-1) <= TA_CANDLEAVERAGE( BodyDoji, BodyPeriodTotal, i-2 ) && // 2nd: doji
TA_REALBODY(i) <= TA_CANDLEAVERAGE( BodyDoji, BodyPeriodTotal, i-2 ) ) { // 3rd: doji
outInteger[outIdx] = 0;
if ( TA_REALBODYGAPUP(i-1,i-2) // 2nd gaps up

/* add the current range and subtract the first range: this is done after the pattern recognition

请参阅此视频。他解释了-100和100。甚至引用了此页面。

** -100表示看跌的Tristar模式,其中中间的蜡烛体位于其他两个蜡烛体上方。相反,+ 100表示看涨的Tristar模式,其中中体位于相邻的下方。
What are the numbers such as -100, +100, -200, +200 and etc, when using ta-lib in Python? **
