For each day, the expression is evaluated and the values in the Alpha output vector represent the weights to allocate to each stock. Alpha weights are not how much you want to buy or sell, but a weighting position you would reach this day. These weights are multiplied by book size (total money invested in the portfolio) to get the dollar value held in each stock. For example, if the Alpha weight (after neutralization and scaling) for MSFT is 0.2423, then we’ll have MSFT stocks with the total value 0.2423*book size.

对于每一天，计算表达式，Alpha输出向量中的值表示分配给每只股票的权重。阿尔法权重不是你想买或卖多少，而是你今天会达到的权重头寸。这些权重乘以账面规模（投资于投资组合的总金额），得出每只股票的美元价值。例如，如果MSFT的Alpha权重（中和和缩放后）为0.2423，那么我们将拥有总价值为0.2423*书本尺寸的MSFT股票。

A Call Option is the right to buy an asset at a predetermined price.
For example, if Company A's stock is currently $60 and you want to buy it at the same price a week later, you can pay the option premium and buy a $60 call option expiring next week. If Company A's stock price rises to $70 at expiration, you can buy the stock with a $10 profit, right? In this case, as expiration approaches, the call option's price itself will rise significantly, resulting in profit.
Therefore, buying call options can bet on asset price increases (long position).

看涨期权是以预定价格购买资产的权利。例如，如果A公司的股票目前为60美元，而你想在一周后以相同的价格购买，你可以支付期权溢价，购买下周到期的60美元看涨期权。如果A公司的股价在到期时上涨到70美元，你可以以10美元的利润购买股票，对吗？在这种情况下，随着到期日的临近，看涨期权的价格本身将大幅上涨，从而带来利润。因此，购买看涨期权可以押注资产价格上涨（多头头寸）。
Options are contracts within the derivatives market, which give the right, but not the obligation, to buy or sell an underlying security at a specific strike price. Since it's a right and not an obligation, the option holder doesn't have to buy or sell the stock when it expires. The amount paid to have this option is called the option premium, which can be simply understood as the price of the option.
Options are good indicators of market participants' psychology and can be useful in exploring Alpha signals. Let's learn some basic knowledge needed to use option data for Alpha exploration.

期权是衍生品市场中的合约，它赋予以特定执行价格买卖标的证券的权利，但不是义务。由于这是一种权利而不是义务，期权持有人在股票到期时不必买卖股票。为获得此期权而支付的金额称为期权溢价，可以简单地理解为期权的价格。期权是市场参与者心理的良好指标，在探索阿尔法信号方面很有用。让我们学习一些使用阿尔法勘探期权数据所需的基本知识。
CLV is an indicator that captures price changes over a day (short-term period). Therefore, it might be more suitable for creating reversion Alphas among the two main branches of PV Alpha (momentum and reversion). Thus, the following idea might be effective:
When CLV is low (close to -1) → Buy position
When CLV is high (close to 1) → Sell position

CLV是一个捕捉一天内（短期）价格变动的指标。因此，在PV Alpha的两大主要分支（动量和反转）中，它可能更适合用于构建反转Alpha。因此，以下想法可能有效：
当CLV接近-1时，买入
