雅虎股票 API 股票行情趋势函数
任何人都可以深入了解雅虎此次通话返回的内容吗？
参考的是 t7 股票走势。
当提交此函数的符号时，雅虎会做出类似于以下内容的响应：
AAPL nbsp;==+-+==nbsp;
我已经在互联网上搜索了此输出的解释，但空手而归。
有人有过这个电话的经验吗？
Can anyone give any insight to what Yahoo returns for this call?
The reference is t7 ticker trend.
When submitting a symbol for this function, yahoo responds with something similar to the following:
AAPL nbsp;==+-+==nbsp;
I have scoured the interwebs to find an explanation of this output, but have come up empty handed.
Anyone have any experience with this call?

AAPL - 股票代码
- 放置在趋势开始和结束处的空间
==++-+== - 股票行情趋势。它由三个部分组成
= : 支付的价格与之前相同
+ : 支付的价格大于之前的交易
- ：支付的价格低于之前的交易价格。
假设一只股票的交易价格为 1.00 美元。下一笔交易价格为 1.01 美元，涨幅为 1.01 美元
因此股票行情趋势将显示+。接下来的两笔交易价格为 1.01 美元，因此
由于价格没有变化，因此将显示为 ==。该股票随后交易于
$1.00，然后 $.99，然后 $.98，这样就会显示 ---。完整的股票趋势将
show +==---
这个的用处是显示趋势。如果股票显示+++++，那么这很清楚地表明人们在排队，并且每个人都愿意比上一个支付更多的钱。该股票可能出了问题。 =====表明市场对股票的价格非常有信心。 +==-+- 有点鱼龙混杂，没有给出任何明确的信号来表明市场对该股票的看法。
AAPL - the stock ticker
- a space placed at the beginning and the end of the trend
==+-+== - the ticker trend. It's made up of three components
= : the price paid is the same as before
+ : the price paid is greater than the trade before
- : the price paid is less than the trade before.
So say a stock trades at $1.00. The next trade is for $1.01 which is an increase
and so the ticker trend would show +. The next two trades are at $1.01 so they
would display as == since there was no change in price. The stock then trades at
$1.00, then $.99, then $.98 so it would show ---. The complete ticker trend would
show +==---
The usefulness of this is to show trends. If the stock shows +++++ then that's a pretty clear indication that people are lined up and each one is willing to pay more than the last. Something is probably going on with that stock. ===== would show that the market is very confident in the price of the stock. +==-+- would be a bit of a mixed bag, not giving any clear signal of what the market thinks of the stock.
