Strategy Application

Purpose and Scope

The Strategy Application is a React-based financial planning tool that provides cryptocurrency trading strategy analysis and calculation capabilities. It implements a ladder-based dollar-cost averaging (DCA) strategy calculator that helps users plan their cryptocurrency investments by modeling worst-case scenarios and calculating key financial metrics.

The application is designed as a multi-step wizard interface that guides users through price input, investment parameters configuration, and comprehensive report generation. For general information about frontend applications, see Frontend Applications. For wallet management and order tracking functionality, see Wallet Application.

Application Architecture

The Strategy Application follows a wizard-based architecture built with React and Material-UI components, utilizing the react-declarative framework for form management and navigation.

Wizard Steps Configuration

The application defines three main wizard steps with corresponding routes:

Step ID	Label	Component	Purpose
price	Цена	PriceView	Cryptocurrency price input
amount	Шаг	AmountView	Investment parameters
report	Отчет	ReportView	Strategy analysis report

Wizard Interface Flow

The application implements a three-step wizard interface that guides users through the strategy calculation process:

Price Input Step

The PriceView component handles cryptocurrency selection and price configuration. It supports five major cryptocurrencies with pre-configured default values and descriptions:

• BTCUSDT: Bitcoin with default price $100,000.00
• ETHUSDT: Ethereum with default price $4,000.00
• BNBUSDT: BNB with default price $600.00
• XRPUSDT: XRP with default price $0.50
• SOLUSDT: Solana with default price $150.00

The component dynamically displays relevant fields based on the selected cryptocurrency symbol and validates user input for price and investment amount.

Strategy Calculation Engine

The core calculation logic is implemented in the generateReport function, which performs ladder-based dollar-cost averaging calculations with commission consideration.

Calculation Process

Key Calculation Parameters

Parameter	Type	Description	Default
fiatAmount	number	Total investment amount in USDT	-
lastClosePrice	number	Current cryptocurrency price	-
ladderPercent	number	Price decrease percentage per step	-
orderPrice	number	Amount invested per step	-
priceGrowthRate	number	Expected daily price growth	1.5%
commissionRate	number	Trading commission rate	0.2%

Validation Logic

The calculation engine implements comprehensive input validation:

// Validation conditions from generateReport.ts:13-24
- fiatAmount > 0
- lastClosePrice > 0  
- 0 < ladderPercent < 100
- 0 < orderPrice <= fiatAmount
- priceGrowthRate > 0
- commissionRate >= 0

Report Generation

The generateReport function produces comprehensive markdown reports with detailed financial analysis and projections.

Report Structure

The generated report includes the following sections:

1. Cryptocurrency Information (# Монета)

   • Symbol and current price
   • Timestamp with timezone

2. Key Metrics (# Метрики)

   • Break-even price calculation
   • Stop price determination
   • Profit target price (20% return)
   • Commission rate information

3. Worst-Case Scenario Table (# Наихудший сценарий)

   • Step-by-step price ladder breakdown
   • Coins purchased at each level
   • Running totals and remaining funds
   • Commission costs per transaction

4. Profitability Analysis (# Доходность в наихудшем сценарии)

   • Expected time to reach profit target
   • Growth rate assumptions and disclaimers

Report Calculation Formulas

The report generation implements several key financial calculations:

// Key formulas from generateReport.ts
const breakEvenPrice = totalSpent / totalCoins;
const stopPrice = steps[steps.length - 1].price;
const targetProfit = fiatAmount * 0.2; // 20% profit target
const profitPrice = (totalSpent + targetProfit) / totalCoins;
const daysToProfit = Math.ceil(
  Math.log(profitPrice / stopPrice) / Math.log(dailyGrowthMultiplier)
);
Copy

Backend Integration

The Strategy Application integrates with the backend API to fetch real-time cryptocurrency prices and supports report downloading functionality.

API Integration Flow

The application uses the /price/close_price endpoint to fetch current cryptocurrency prices, which are then used as default values in the price input form.

Download Functionality

The ReportView component implements markdown report downloading through the downloadSubject subscription mechanism, allowing users to save their strategy analysis reports locally.
