Method

BigDecimalgetPercentage(BigDecimal amount, BigDecimal percent)
get Percentage 
return divide(amount.multiply(percent), ONE_HUNDRED);
BigDecimalgetPercentageValue(BigDecimal price, double amount)
get Percentage Value 
return price.multiply(new BigDecimal(amount / 100));
BigDecimalgetProfit(BigDecimal ask, BigDecimal bid, BigDecimal fee)
Get the profit of an operation from its ask/bid and fees values 
BigDecimal one = new BigDecimal(1);
BigDecimal oneMinusFee = one.subtract(fee);
BigDecimal omfPow = oneMinusFee.multiply(oneMinusFee);
BigDecimal profit = ask.divide(bid, 8, RoundingMode.FLOOR).multiply(omfPow).subtract(one);
return profit;
BigDecimalgetProzentWert(BigDecimal zahl, BigDecimal prozentsatz, int nachkommastellen)
Den Wert eines Prozentsatzes einer Zahl berechnen, kaufmaennisch auf n Nachkommastellen gerundet. 
BigDecimal prozentsatz2 = prozentsatz.movePointLeft(2);
BigDecimal result = zahl.multiply(prozentsatz2);
return rundeKaufmaennisch(result, nachkommastellen);
BigDecimalgetRandomBigDecimal(BigDecimal a, BigDecimal b)
get Random Big Decimal 
double randomNum = Math.random();
return a.add((b.subtract(a)).multiply(new BigDecimal(randomNum)));
BigDecimalgetRandomBigDecimal(int maxValue, int scale)
get Random Big Decimal 
Random generator = new Random();
double d = (double) generator.nextInt(maxValue) + generator.nextDouble();
BigDecimal decimal = new BigDecimal(d);
BigDecimal result = decimal.setScale(scale, RoundingMode.FLOOR);
return result;
BigDecimalgetRandomPriceChangeFactor(BigDecimal currentPrice)
get Random Price Change Factor 
if (currentPrice.compareTo(PENNY_STOCK_P) == -1 || currentPrice.compareTo(PENNY_STOCK_P) == 0) {
    return JUNK_STOCK_MIRACLE_MULTIPLIER;
} else if (currentPrice.compareTo(STOCK_P_HIGH_BAR) == 1 || currentPrice.compareTo(STOCK_P_HIGH_BAR) == 0) {
    return STOCK_P_HIGH_BAR_CRASH;
BigDecimal factor = BigDecimal.valueOf(0);
Random rand = new Random();
int y = rand.nextInt(STOCK_CHANGE_MAX_PERCENT.subtract(BigDecimal.ONE).intValue());
...
intgetRecordSize(List> columnBaseData)
get Record Size 
if (columnBaseData == null || columnBaseData.size() == 0) {
    return 0;
if (columnBaseData.get(0) == null) {
    return 0;
return columnBaseData.get(0).size();
doublegetRSBigDecimal(Object object)
getRSBigDecimal, get fields value from a object 
if (object == null)
    return (double) 0;
return ((BigDecimal) object).doubleValue();
intgetScale(BigDecimal bd1, BigDecimal bd2)
get Scale 
int scale1 = 0;
int scale2 = 0;
if (bd1 != null) {
    scale1 = bd1.scale();
if (bd2 != null) {
    scale2 = bd2.scale();
return (scale1 > scale2 ? scale1 : scale2);
