Fibonacci Trading Python

[Zee Palmer]

Generallythe practice is called inter-op as in Rust Python Inter-op. The most thorough, but not necessarily the most up-to-date, reference I know of is here. A closely related topic is broached frequently on Discourse related to FFI.

The context of the application are very simple trading algorithms. In Rust I open a stream to the Binance API using a websocket, and every time new candlestick data is received the Python code gets executed in Rust.

But if all your calculations are in pandas/numpy, then making the python faster isn't going to help much anyway. You might be able to improve things a little bit by removing python entirely and rewriting it in something like polars, but if you want maximum performance you'll need to write rust code that's custom-made for your data.

I'll share everything I know about Python as it relates to the code you've shared. The two libraries you are importing are (over generalizing) possible the most optimized libraries in Python. Pandas is based on R dataframes which also uses C. Both numpy and pandas make extensive use of lowered C function calls. Python was invented as a wrapper for C and that's exactly what those libraries are using it for. Numerous benchmarks compare Rust to numpy data processing performance and the results depend strongly on using the unique advantages Rust has over Python, such as data ingestion and munging, and largely irrespective of those function calls to numpy which, realistically, cannot be optimized further without doing wildly unsafe array operations.

The Fibonacci series in python is a mathematical sequence that starts with 0 and 1, with each subsequent number being the sum of the two preceding ones. In Python, generating the Fibonacci series is not only a classic programming exercise but also a great way to explore recursion and iterative solutions.

Memoization is a method that speeds computer programs or algorithms by storing the results of expensive function calls and returning the cached result when the same inputs occur again. It is useful in optimizing the Fibonacci series in Python calculations as the recursive approach recalculates the same Fibonacci numbers many times, leading to inefficiency.

This program defines a function Fibonacci that generates a Fibonacci sequence up to the specified length n. The sequence is then printed for the first 10 Fibonacci numbers, but you can change the value of n to generate a different number of Fibonacci numbers.

In Fibonacci series calculations in Python, without memoization, the recursive algorithm recalculates the same numbers repeatedly. Memoization addresses this inefficiency by storing the results. When the function is called again with the same input, it utilizes the previously calculated result for the problem, enhancing the efficiency of the Fibonacci series computation.

Dynamic programming is a strategy used to solve problems by breaking them down into smaller subproblems and fixing each subproblem only once, storing the results to avoid redundant calculations. This approach is very effective for solving complex problems like calculating Fibonacci numbers successfully.

Efficient Reuse: By storing intermediate results, dynamic programming avoids redundant calculations. Each Fibonacci number is calculated once and then retrieved from memory as and when needed, enhancing efficiency.

Space optimization strategies for calculating Fibonacci numbers aim to reduce memory utilization by storing only the important previous values rather than the entire sequence. These techniques are especially useful when memory efficiency is a concern.

Space Efficiency: Space-optimized approaches use much less memory because they store only a few variables (generally two) to keep track of the latest Fibonacci numbers. This is relatively space-efficient, making it suitable for memory-constrained environments.

The Fibonacci sequence has many real-world applications. In nature, it describes the arrangement of leaves, petals, and seeds in plants, exemplifying efficient packing. The Golden Ratio derived from Fibonacci proportions is used to create aesthetically desirable compositions and designs. In technology, Fibonacci numbers play a role in algorithm optimization, such as dynamic programming and memoization, enhancing performance in responsibilities like calculating massive Fibonacci values or solving optimization problems, particularly in the context of Fibonacci series in Python. Moreover, Fibonacci sequences are utilized in financial modeling, assisting in market analysis and predicting price trends. These real-world applications underscore the significance of the Fibonacci series in mathematics, nature, art, and problem-solving.

Fibonacci plays a crucial role in trading and finance through Fibonacci retracement and extension levels in technical analysis. Traders use these levels to identify potential support and resistance points in financial markets. The Fibonacci series helps in predicting stock market trends by identifying key price levels where reversals or extensions are likely. Fibonacci trading techniques involve using these levels in conjunction with technical indicators to make knowledgeable trading decisions. Traders regularly look for Fibonacci patterns, like the Golden Ratio, to help assume price movements.

While seemingly rooted in mathematics, the Fibonacci series in Python also has relevance in data science. Understanding the principles of sequence generation and pattern recognition inherent in the Fibonacci series can aid data scientists in recognizing and analyzing recurring patterns within datasets, a fundamental aspect of data analysis and predictive modeling in data science..

At times it feels like traders give the Fibonacci trading sequence an almost mystical power. Yet, despite its mysterious accuracy in trading and in nature, Fibonacci is nothing more than simple retracement levels. These levels are the only representative of where a security could have a price reaction, but nothing is etched in stone.

On the contrary, some day trading experts see these Fibonacci numbers as a short-sell strategy. For instance, if GE stock is at $21 and falls to $20.62, some Fibonacci traders may see the 38 cent drop as a good sign to short the stock.

While some financial experts are skeptical of the Fibonacci strategy, it has predicted other downturns before. In February before the COVID-19 crisis, the Dow Jones retraced about 50% before the economic crash. Andrew Adams is a technical analyst at Saut Strategy. He wrote in a research note that the pullback at that ratio meant an end to the previous bull market.

Before we go into the gritty details about Fibonacci trading strategies, it is worth our time to discuss the different types of fibonacci trading personas you might encounter. While mostly fictitious, these three personas do an awesome job of summarizing common trading practices.

Depending on what the market is offering, you might fluctuate between the low and high-volatility Fibonacci trader. Or, you may find yourself only using Fibonacci as an ancillary tool to support your trade plan thesis.

Fibonacci assists in seeing hidden levels of support and resistance to help you determine your entry and exit targets. To what degree you emphasize these levels depends upon your own conviction with the tool.

Here is an example of the Fibonacci in nature with this seashell. The volume of each part of the shell matches exactly the Fibonacci numbers sequence. Thus, each part of this shell is 61.8% of the next.

This ratio is not only found in animals and flowers. This ratio is literally everywhere around us. It is in the whirlpool in the sink, in the tornados when looked at through satellite in space or in a water spiral.

The Fibonacci ratio is constantly right in front of us and we are subliminally used to it. Thus, the human eye considers objects based on the Fibonacci ratio as beautiful and attractive.

Do you see how each pullback is greater than 78.6% from the initial range? This level of retracement repeatedly produces a choppy pattern. Therefore, you would not want to have lofty profit targets on a trade while the stock is in a tight trading range.

Therefore, you need to prepare for when things go wrong. In a pullback trade, the likely issue will be the stock will not stop where you expect it to. It may pull back to a full 100% retracement, or it could even go negative on the date.

If that is 5 minutes or one hour, this now becomes your time stop. If there is only a 15% chance you will walk away a winner, just exit the trade with a predetermined allowable loss percentage or right at the market.

As a general rule, we prefer 10%. But since we only use a small portion of the account size for each position, this keeps a total portfolio loss of under 2%. With lower volatility stocks, this may trigger a stop only once or twice a year.

This Fibonacci trading strategy includes the assistance of the well-known MACD. Here we will try to match the moments when the price interacts with important Fibonacci levels in conjunction with MACD crosses to identify an entry point.

As a trader, when you see the price coming into a Fibonacci support area, the biggest clue you can look to is the volume to see if that support will hold. Notice how in the above chart the stock had a number of spikes higher in volume on the move up, but the pullback to support at the 61.8% retracement saw volume plummet.

Fibonacci time zones are based on the length of time a move should take to complete, before a change in trend. You need to pick a recent swing low or high as your starting point and the indicator will plot out the additional points based on the Fibonacci series.

Unfortunately, with Fibonacci trading, you begin to expect certain things to happen. For example, if you see an extension as the price target, you can become so locked on that figure you are unable to close the trade waiting for bigger profits.
