  1. Same correction needs to occur in the sellStock() function

    ns.print(‘SOLD: ‘+ stock + ‘quant: ‘+ portfolio[i].shares +’@ ‘+ portfolio[i].value);

    I really like the script though and appreciate you sharing it. It gives me an idea of how to use the TIX APIs.

    • Another issue I found is that stockBuyQuantCalc() can return a negative shares number. I had to add a logical && shares > 0 under buyStock(). I also liked the idea of the other commenter where you keep a rolling percentage available. I made minimumCash a global var and added: minimumCash = (ns.getServerMoneyAvailable(“home”) * 0.3) to the stockBuyQuantCalc() for real time updating.

      function buyStock(stock) {
      let stockPrice = ns.stock.getAskPrice(stock); // Get the stockprice
      let shares = stockBuyQuantCalc(stockPrice, stock); // calculate the shares to buy using StockBuyQuantCalc

      if (ns.stock.getVolatility(stock) 0) { // if volatility is < 5%, buy the stock
      ns.stock.buy(stock, shares);
      ns.print('Bought: ' + stock + ' quant: ' + Math.round(shares) + ' @ ' + Math.round(stockPrice));

      portfolio.push({ sym: stock, value: stockPrice, shares: shares }); //store the purchase info in portfolio
      }
      }

  2. Rather than use a static number for the reserve cash, I use a percentage. That way, as you have more assets (including stocks), you’ll have a larger reserve of cash to use. At the same time, when you are BELOW the minimum, it can make small purchases and sales and bring you back up. I do 10% reserve, and that does pretty darn well

  3. Thank you for publishing your script. I used it to become familiar with the ns.stock methods very quickly. I think there is one error in your code in line 31:

    “if(ns.stock.getAskPrice(stock) >= portfolio.value*1.1){
    sellStock(stock);
    }”

    Obviously you want to write “portfolio[i].value”.

    “portfolio.value” returns “null”, since portfolio is an array of objects, not an object itself.

    Greetings!
