 The win rate $W$ is the proportion of winning trades with respect to all the trades made by a strategy. We use the following function to compute the win rate:
 
-$$W = \frac{\sum^{o \in T_{win}} o}{N}$$
+$$W = \frac{|T_{win}|}{N}$$
 
 Where $W$ is the win rate, $N$ is the number of trades and, $T_{win}$ is the set of all trades where the strategy made money.
 
 Similarly, we can compute the rate of losing trades:
 
 $$ 
-    L = \frac{\sum^{o \in T_{lose}} o}{N} 
+    L = \frac{|T_{lose}|}{N} 
 $$
 
 Where $L$ is the lose rate, $N$ is the amount of trades made and, $T_{lose}$ is the set of all trades where the strategy lost money. Note that the above formula is the same as calculating $L = 1 – W$ or $W = 1 – L$

     Let's say that you think that the price of *stonecoin* today is $10.0. You believe that, because they will start mining stonecoin, it will go up to $15.0 tomorrow. There is the risk that the stone is too hard, and the GPUs can't mine it, so the price might go to $0 tomorrow. You are planning to invest $100.<br>
