Volatility is calculated using the relative volatility index
Market Control is calculated using exponential moving averages and the percent of the strength is based on how many bars the market goes on in that trend.
Market Strength is calculated with RSI and will change colour if it is overbought (red) or oversold (green)
Money Index is calculated with Money Flow Index
Rate of Change is calculated with ROC but it cannot go to a negative number and the max it can go up to is a 100%.
