Check Bitcoin Price Movements! Find Buying and Selling Opportunities with the "Volatility Ratio"
This method analyzes the intensity of price movements (volatility) by looking at a 5-minute Bitcoin price chart. We use this to identify opportunities for when to buy and when to sell. It involves examining how volatile the current price movements are compared to historical data.

Momentum Oscillator Theoretical Background
The core concept behind this strategy is that "momentum tends to continue for a while." If prices are rising strongly, they might continue to rise. Conversely, if prices are falling rapidly, they might continue to fall. Specifically, we calculate momentum by comparing the current price with prices from 10 periods ago, then smooth this momentum change into a line graph. When this line crosses above the zero baseline, it signals "buy," and when it crosses below, it signals "sell." In other words, it's a strategy that tries to ride the "upward trend!"
Specific Trading Rules (This Verification)
Entry Conditions
- When the momentum line crosses above the zero line (upward momentum is emerging, so it's time to buy)
- When the momentum graph is above the zero line (upward momentum is continuing, so it's time to buy)
Exit Conditions
- When the momentum line crosses below the zero line (upward momentum is weakening, so it's time to sell)
- When the momentum graph is below the zero line (momentum is disappearing, so it's time to sell)
Risk Management
This strategy was missing a very important rule: the "stop-loss" rule that says "if losses reach this point, give up and sell." Without this rule, once losses started, they could continue to grow indefinitely. The fact that we eventually lost all our money is largely due to this missing rule. To avoid large losses, stop-loss rules are absolutely essential.
Reproduction Steps (HowTo)
- Install Python and dependencies (ccxt, pandas, ta)
- Fetch and preprocess BTC/USDT OHLCV data using ccxt
- Calculate indicators needed for the strategy (using ta, etc.)
- Generate trading signals from thresholds and crossover conditions
- Verify and evaluate considering fees and slippage

Why This Result Occurred (3 Reasons)
- 1With this method, we made a total of 5802 trades, but only about 9 out of every 100 trades were profitable (a win rate of 9.31%), which is very low. This made it difficult to generate profits.
- 2On average, each trade resulted in a loss of 0.4% (a negative expectancy). This means money was gradually decreasing with each trade, which is one of the reasons for the total loss of 100% in the end.
- 3Comparing the profit and loss amounts, the profits were very small. This might indicate that the money paid for fees and other costs was significantly higher than the money gained from winning trades.
3 Lessons Learned from This Result
- 1We learned that even with a high-frequency trading approach, it's difficult to achieve overall profitability if the win rate is low or the average profit per trade is negative.
- 2We realized the importance of combining volatility measurement methods with other strategies, not relying on just one.
- 3We understood that analyzing the reasons for failure and considering improvements is crucial for developing better strategies.
Specific Risk Management Methods
How to Determine Position Size
This strategy didn't seem to have rules for how much money to use per trade. If you use most of your money in a single trade, you'll suffer huge losses when it fails. Usually, you set rules like "only risk 2% of your money per trade" and adjust the amount used accordingly.
How to Handle Large Losses
The fact that we lost 100% at our worst point (max DD) was because there was no mechanism to stop losses from growing. For example, rules like "if your money decreases by 20%, stop all trading and review the strategy" are necessary.
Capital Management Methods
This strategy lacked the concept of "capital management" - how to protect and use money. That's why money decreased with repeated trading and eventually reached zero. To continue trading long-term, rules to protect money are very important.
Specific Improvement Proposals
- First and most important is to add "stop-loss" rules. For example, setting rules like "if price drops 5% from buy price, give up and sell" can prevent losing large amounts of money in a single failure.
- Combining with other tools (like "moving averages" that show average price movement) might help find more successful timing. Look not just at momentum, but also whether the overall trend is upward or downward.
- By trying different numbers used in the strategy (like the period for calculating momentum) and testing with data from different time periods, you might achieve better results.
Improving Practicality (Operational Considerations)
- When tested with historical data, this strategy produced very poor results. Using it with real money as-is would be extremely dangerous.
- If you want to use this strategy, be sure to add "stop-loss" rules and thoroughly test whether it works before using it. Using it as-is has a very high probability of losing all your money.
- Cryptocurrency trading involves very volatile price movements. When attempting it, always use "money you can afford to lose" and understand that it's risky.
Verification Transparency and Reliability
- Data Source: This strategy was tested using historical 5-minute price data of the cryptocurrency "Solana (SOL)" to see if it would work.
- Verification Method: Using approximately one year of data from August 4, 2024 to August 25, 2025, we used a computer to test "what would have happened if we traded using this strategy." We analyzed those results.
- Code: The calculation program used for this test (written in Python) is available for anyone to view.
- Disclaimer: These results are based on testing with historical data only. Future performance is not guaranteed to be the same. Investment always carries the risk of losing money. Please think carefully and make your own judgments.
