Thread: How to solve this problem in Programming

I'm a beginner, please note, I have the following problem and I didn't find a solution on how to solve it, I'm trying to create this, what is the most appropriate way to solve this?

A bank has a portfolio of thousands of trades and they need to be categorized.
A trade is a commercial negotiation between a bank and a client.
Each trade has a value that indicates the transaction amount in dollars and a text indicating if the client´s sector is "Public" or "Private". They implement the following interface:

interface ITrade
{
double Value { get; }
string ClientSector { get; }
}

Currently, there are three categories:
LOWRISK: Trades with value less than 1,000,000 and client from Public Sector
MEDIUMRISK: Trades with value greater than 1,000,000 and client from Public Sector
HIGHRISK: Trades with value greater than 1,000,000 and client from Private Sector

Imagine you receive a list of trades and you need to return a list of categories as below:
input: List<ITrade> portfolio
output: List<string> tradeCategories

Example:
Input:
Trade1 {Value = 2000000; ClientSector = "Private"}
Trade2 {Value = 400000; ClientSector = "Public"}
Trade3 {Value = 500000; ClientSector = "Public"}
Trade4 {Value = 3000000; ClientSector = "Public"}
portfolio = {Trade1, Trade2, Trade3, Trade4}

Output:
tradeCategories = {"HIGHRISK", "LOWRISK", "LOWRISK", "MEDIUMRISK"}

Keep in mind that category rules may be added/removed/modified in the future and be highly complex.
Please write your answer in pseudo-code showing clearly what classes, interfaces, methods and design patterns you would create/use to solve this problem. Also, object oriented programming is appreciated.

what I tried: I read this whole tutorial that explains what pseudo code is and uses java as an example: https://www.geeksforgeeks.org/how-to...a-pseudo-code/, but I don't know how to do it.

some code: if (Trade.index(I).tradeValue < 1000000 and Trade.index(I).client ==< publicSector) Print (low risk)

my instructor is on a 30-day vacation, I really need help
