Create buy/sell signal strategy for a portfolio of stocks

I am looking for a skilled freelancer to create a buy/sell signal strategy for a fixed portfolio of stocks. The strategy will focus on medium-term trading, with a time frame of weeks to month, but shorter term could also be of interest if the results are good enough. The main focus is stocks on the Scandinavian stock market. The signal strategy should prove to be efficient over a 5 year time period and preferably perform similarly well on unseen data. The signals could be based on either TA-Lib, pandas_ta or FinTA technical indicators, but could also be generated from scratch in python as long as OHLCV-values are sufficient as input.

Requirements:
- Experience in developing buy/sell signal strategies for medium-term trading
- Proficiency in analyzing stock market trends and indicators
- Ability to work with a specific list of stocks provided by the client
- Knowledge of high-risk trading strategies, with a focus on potential for significant gains and losses

Ideal Skills and Experience:
- Strong background in stock market analysis and technical analysis
- Proven track record in developing successful short/medium-term trading strategies

If you have the necessary skills and experience to develop a short/medium-term buy/sell signal strategy for a specific list of stocks, please submit your proposal.
