# Return Formula

R(n) = (CP(n) - OP(n)) / OP(n)

Where:
	- R(n) = Return in period n
	- CP(n) = Close price
	- OP(n) = Open price

# Rainbow logic

uptrend = 8 EMA(exponential ma) > 21 EMA > 34 EMA > 50 SMA(simple ma) > 100 SMA > 200 SMA
downtrend = 8 EMA < 21 EMA < 34 EMA < 50 SMA < 100 SMA < 200 SMA

# Average True Range
- ATR tells us of opportunities within a particular day but also whether Vol as ben increasing or decreasing
- ATR = the average of x true range values 
  
TR(x) = (High-Low)(x)

ATR(x) = (TR + TR [...] - x) / open - x                  ***** REVIEW
