First automation

Buy one share of AAPL, no logic. This is the simplest automation you can build. Every time you run this it will generate one order => buy one share of AAPL

(def symbol "AAPL")
(buy {symbol} 1)

;;=> {symbol: "AAPL", units: 1, side: "long", ...}

Some logic

This automation has some logic. Calculates Simple Moving Average for the last 21 days and buys one share only if the asset current price is over SMA21 if not closes all positions

(def asset "MSFT")                  ;; define asset
(def sma21 (sma 21 asset))          ;; calculates SMA21
(def closePrice (:close {asset}))   ;; gets asset close price

(if (> closePrice sma21)
  (buy {asset} 1)                     ;; yes => Buy one share
  (closePositions openPositions)      ;; no => Close all open positions
)

Multiple assets

This automation sorts a list of assets by CMR (cumulative total return) and picks top 2 to invest.

(def topX 2)
(def weight (/ 1 topX))
(def stocks [
  "MSFT",
  "ADBE",
  "ADSK",
  "CRM",
  "AAPL"
])

;; define a function to calculate CMR for 21 days
;; for a specific symbol
;; you can use it like (cmr21 "AAPL") will give you [AAPL, x.xxx]
(defn cmr21 [symbol] [symbol, (cmr 21 symbol)])

;; calculates CMR21 for all stocks
(def mAll (map cmr21 stocks))

;; sort descendend by CMR
(def second (fn [val] (* -1 (nth 1 val))))
(def stocksSorted (sortBy second mAll))

;; buy TOP topX
(loop item in (take topX stocksSorted)
  (def symbol (nth 0 item))
  (def amount (* (:capital portfolio) weight))
  (buyAmount {symbol} amount true)
)
