Let’s see how to handle an incoming Forex financial news:
”The safe-haven yen and Swiss franc were higher, with USD/JPY sliding 0.41% to 112.01, just off the previous session's two-month peak of 112.72, while USD/CHF fell 0.21% to trade at 0.9687.Elsewhere, EUR/USD gained 0.20% to trade at 1.1965, while GBP/USD edged down 0.10% to 1.3569, off Monday's 15-month highs of 1.3620.”
Checked the sentences of this news, we found these keywords and phrases:
- number and percentage
- USD/JPY, USD/CHF, EUR/USD, GBP/USD
- and, higher, sliding to, off peak of, fell to, gained to, edged down to, off highs of

Therefore, we should build various Knowledge Processing Units (KPUs) to handle numbers, symbols of Forex instruments and phrases of their movements. The first layer of KPUs handles words, the second layer of KPUs combines words to phrases and the last layers of KPUs processes the meaning of the sentences.
When a KPU finds the price of an forex instrument in the sentence, it should store this last price, change and date in memory and then computes all technical analysis indicators like Moving Average, Variance, RSI, MACD, Bollinger Band indicator,.. etc. Also, the KPUs can process correlation coefficients between various financial instruments.
The KPUs in charge of Robo-Advisor strategies should check the movements of the financial instruments to see how will they affect others and how much. Based on these predictions the final judgement of buying or selling financial instruments will be generated.
Also, the following rules should be defined:
- If the instrument A is up or down, then we should buy or sell what financial instruments and how many?
- What are mean-variances of all financial instruments?
- What are buying and selling points of all financial instruments?
- What is the optimal leverage ratio?
Financial Calculation Algorithms
Basic financial calculation algorithms like what I’ve implemented in the wealth management calculators website CubicPower.idv.tw covering various aspects should also be included. Such as:
Time Value of Money:
Money generates interest in a saving account. So the money of the present time will be worth more than the same amount of money in the future. To interchange the values of two periods, compounding is used to convert present value to the future value of money and discounting is to convert the future money to present value.

figure : Risk and return of three asset classes combination
We can use the above tools to calculate the risks and rewards of different combination ratios of three asset classes - equities, fixed income and cash equivalents. A Robo-Advisor is in charge of portfolio management of these assets. The idea of efficient frontier should also be built into it.
Annuity Future Value
Annuity Present Value
Investment Return Rate
An annuity is a group of fixed amount of cash flows within a period of time. We can discount each individual flow into its present value and add them up to get the present value of the annuity. This is the way to evaluate the annuity. We can calculate the present and future values of the annuity easily with these tools.

Current Bond Price
Coupon Bond Price
Coupon Bond Yield
Zero Coupon Bond Price
Bondholders receive a fixed amount of interest in every period. Therefore, bond prices will change when interest rates changed. When the interest rate goes down, bonds become more valuable, so their prices will go up.
