[The elevator doors open, revealing the Men in Black headquarters, a huge, multileveled, of sixties design, polished steel and glass. The workplaces are sleek and uncluttered, manned by both humans and aliens. Most of the aliens stay in the background, like the upside-down guy who walks on the ceiling, shuffling papers.] [KAY and EDWARDS step off the elevator and onto a platform that looks out over the whole place.] [Kay leads him down into the complex. First, they walk past a sort of passport control center, where a human BUREAUCRAT at a desk is checking the documents of a line of ALIENS who've just arrived. There are a dozen bizarre life forms in that line, CHATTING in half a dozen different alien tongues. Edwards slows as they pass, listening to the PASSPORT CONTROL OFFICER as he addresses an Arquillian, a large, humanoid visitor.]

I don't get business. I have a degree in math and I was an average student in school and college. I'm currently unemployed and quite desperate. I really want to venture here but whenever I read articles on the internet its like my mind goes blank. I'm unable to understand how to manage and start one. Any idea never progresses past the first stage. I'm unable to execute the plan. Please help me. Anyone.

Returns various parameters related to regression function; ts_regression(est_netprofit, est_netdebt, 252, lag = 0, rettype = 2);
Taking the data from the past 252 trading days (1 year), return the β coefficient from the equation when estimating the est_netprofit using the est_netdebt.

Rank the values of x for each instrument over the past d days, then return the rank of the current value + constant. If not specified, by default, constant = 0.
>> Operators
>> Operators
Returns product of x for the past d days; ts_product(x, d) can be used to calculate geometric mean of data fields. The geometric mean is generally a better method for averaging rates of return, growth rates of fundamentals. For example, geometric mean of daily stock returns for past 10 days can be calculated as: power(ts_product(returns, 10), 1/10)
>> Operators
>> Operators
Returns the linear decay on x for the past d days. Dense parameter=false means operator works in sparse mode and we treat NaN as 0. In dense mode we do not.

>> Operators
Returns correlation of x and y for the past d days; ts_corr(vwap, close, 20);Pearson correlation measures the linear relationship between two variables. It's most effective when the variables are normally distributed and the relationship is linear.

返回过去d天x和y的相关性；ts_corr（vwap，关闭，20）；皮尔逊相关系数衡量两个变量之间的线性关系。当变量呈正态分布并且关系是线性时，它最有效。
This operator returns x – ts_mean(x, d), but it deals with NaNs carefully；
Example:
If d = 6 and values for past 6 days are [6,2,8,5,9,NaN] then ts_mean(x,d) = 6 since NaN are ignored from mean computation. Hence, ts_av_diff(x,d) = 6-6 = 0
>> Operators
>> Operators
Returns the relative index of the min value in the time series for the past d days; If the current day has the min value for the past d days, it returns 0; If previous day has the min value for the past d days, it returns 1. If d = 6 and values for past 6 days are [6,2,8,5,9,4] with first element being today’s value then min value is 2 and it is present 1 days before today. Hence, ts_arg_min(x, d) = 1

返回过去d天时间序列中最小值的相对索引；如果当前日期具有过去d天的最小值，则返回0；如果前一天具有过去d天的最小值，则返回1。如果d=6，过去6天的值为[6,2,8,5,9,4]，第一个元素为今天的值，则最小值为2，并且在今天之前1天存在。因此，ts_arg_min（x，d）=1
Returns the relative index of the max value in the time series for the past d days. If the current day has the max value for the past d days, it returns 0. If previous day has the max value for the past d days, it returns 1；If d = 6 and values for past 6 days are [6,2,8,5,9,4] with first element being today’s value then max value is 9 and it is present 4 days before today. Hence, ts_arg_max(x, d) = 4
