"A Formula to Predict the Future?" We Tried Trading Bitcoin and This Happened

This time, we experimented with a strategy of buying and selling Bitcoin at very short intervals, specifically every 5 minutes. This strategy uses a special calculation method called the "Inverse Fisher Transform," said to indicate price momentum. However, the results were unfortunately not very good. Let\'s dive in and see why it didn\'t work out!

Introduction and Prerequisites

This time, we experimented with a strategy of buying and selling Bitcoin at very short intervals, specifically every 5 minutes. This strategy uses a special calculation method called the "Inverse Fisher Transform," said to indicate price momentum. However, the results were unfortunately not very good. Let\'s dive in and see why it didn\'t work out!

[Verification] Strategy Backtest Overview

  • Strategy Name: Trend Following Strategy using Inverse Fisher Transform
  • Asset: BTC/USDT
  • Timeframe: 5m
  • Period: 2024-07-21 to 2025-08-25 (399 days)
  • Initial Capital: $10,000
  • Fees/Slippage: 0.1% / 0.1%
  • Exchange: binance

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)

  1. Install Python and dependencies (ccxt, pandas, ta)
  2. Fetch and preprocess BTC/USDT OHLCV data using ccxt
  3. Calculate indicators needed for the strategy (using ta, etc.)
  4. Generate trading signals from thresholds and crossover conditions
  5. Verify and evaluate considering fees and slippage

Why This Result Occurred (3 Reasons)

  1. 1Because we won very few trades. Out of 10 attempts, we only won 3 times. We lost money on most trades.
  2. 2Because, on average, each trade resulted in a small loss of money. Repeating this process leads to a continuous decrease in capital.
  3. 3Because at our worst point, we experienced a significant loss, losing almost all of our capital (96%). This was a very dangerous situation.

3 Lessons Learned from This Result

  1. 1A strategy must aim for large wins that can recover all losses from multiple small losses, even with just a single win.
  2. 2Instead of jumping in solely based on a signal that "now is the chance," it's crucial to consider the overall economic climate and broader market trends.
  3. 3Even the most sophisticated formulas can fail when unexpected news or events occur.

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.

Frequently Asked Questions

Q.Is this "Inverse Fisher Transform" some kind of magic spell?

A.No, it's not a magic spell! It's the name of a mathematical calculation method used to "make price momentum easier to see."

Q.Isn't trading Bitcoin every 5 minutes too short?

A.Exactly! Trading every 5 minutes involves very rapid price movements, like a roller coaster. This makes it extremely difficult to predict the next move, often leading to losses.

Q.A 30% win rate means losing most of the time, right?

A.Yes, that's correct. If you attempt 10 trades, it calculates that you'll lose 7 of them. This is a pretty tough performance.

Q.What does PF stand for, and is it good or bad performance?

A.PF stands for "Profit Factor," which is like a report card for a trading strategy. It's calculated by dividing the total profit by the total loss. If the number is greater than 1, it indicates profitability. However, our result was much smaller than 1, showing that the total losses were greater than the total profits.

Q.HODL is an interesting name, what does it mean?

A.It's a sort of codeword used in the world of cryptocurrencies like Bitcoin, meaning "I'm going to hold on tight, no matter what!" Interestingly, in this experiment, the "HODL" strategy, which simply involves buying and holding, performed better than our frequent trading strategy.

Q.What period and timeframe were used for verification?

A.Verified using 5m candles. Please check the overview section in the article for the specific period.

Q.What were the final return and maximum drawdown?

A.Final return was 0.00% and maximum DD was 0.00%.

Q.What were the win rate and PF?

A.Win rate was 0.00% and profit factor was 0.00.

Q.How did it compare to HODL?

A.HODL comparison for the target period is omitted.

Q.Were fees and slippage considered?

A.Yes. Backtest settings for fees and slippage are reflected in the profit/loss calculations.

Q.Was the market environment more trending or ranging?

A.The period appears to have been range/decline dominant.

Q.Can beginners handle this strategy?

A.It can be handled with basic knowledge of indicators and backtesting environments. Start with small amounts or demo trading.

Q.What risk management is recommended?

A.We recommend stop-loss and position sizing considering max DD, plus setting system halt criteria.

Q.Can we expect similar future results?

A.Past results do not guarantee future performance. Results depend heavily on market conditions and parameter suitability.

Q.What are the improvement directions?

A.Consider combining trend and volatility filters, re-optimizing parameters, and controlling trading frequency.
