This strategy mainly utilizes moving averages and Bollinger Bands to capture market trends and volatility. It employs three different types of moving averages: Simple Moving Average (SMA), Weighted Moving Average (WMA), and Exponential Moving Average (EMA). At the same time, it uses Bollinger Bands to set price channels, with the upper and lower bands serving as signals for opening and closing positions. When the price breaks through the upper Bollinger Band, it opens a short position; when it breaks through the lower band, it opens a long position. It also sets wider Bollinger Bands as stop-loss levels, closing positions when the price breaches these bands. Overall, this strategy attempts to establish positions promptly when trends emerge and decisively cut losses when risks escalate, aiming to achieve stable returns.

- Calculate three moving averages with different periods: slow SMA, fast EMA, and medium WMA, reflecting the long-term, short-term, and medium-term market trends respectively.
- Compute two sets of Bollinger Bands based on price standard deviation: entry Bollinger Bands (with narrower distance between upper and lower bands) and stop-loss Bollinger Bands (with wider distance). Entry bands are used for opening positions, while stop-loss bands are used for closing positions.
- When the fast EMA crosses above the upper entry Bollinger Band, open a short position; when the fast EMA crosses below the lower entry Bollinger Band, open a long position. This implies that the price has deviated significantly from the mean and a trend may emerge.
- Once a position is open, if the price further crosses above the upper stop-loss Bollinger Band, close all long positions; if the price further crosses below the lower stop-loss Bollinger Band, close all short positions. This is to control losses and decisively stop loss once the trend reverses.
- The above process is repeated continuously, allowing the strategy to flexibly adjust positions according to market trends and stop losses in a timely manner, in order to achieve robust returns.

- It considers three moving averages of different speeds, comprehensively capturing market trends at various levels.
- It introduces Bollinger Bands as conditions for opening and closing positions, which can be dynamically adjusted according to market volatility, flexibly adapting to market conditions.
- It sets stop-loss Bollinger Bands to control drawdowns and decisively closes positions when the market fluctuates dramatically, avoiding amplified losses.
- The logic is clear and the rules are simple, easy to implement and optimize.
- It has a wide range of applications and may be effective for various markets and time periods.

- In a sideways market, frequent opening and closing of positions may lead to substantial transaction costs, eroding profits.
- At the initial stage of a trend reversal, the strategy may still trade in the direction of the original trend, resulting in certain losses.
- For extreme market conditions, such as rapid price gaps, the stop-loss Bollinger Bands may not effectively control risks.
- Improper parameter selection (such as moving average periods, Bollinger Band widths, etc.) may invalidate the strategy.
- If the market continues to fluctuate, the strategy may not be able to capture significant trend opportunities for an extended period.

- Appropriately increase the parameters of moving average periods and Bollinger Band widths to reduce trading frequency and costs in a sideways market.
- Introduce more technical indicators or market sentiment indicators as filters to improve the accuracy of entry signals and avoid losing trades that may occur at the beginning of a trend.
- Set special rules for extreme market conditions, such as suspending new positions when gaps occur, to control risks.
- Optimize parameters to find the most suitable combination for the current market, enhancing the robustness of the strategy.
- Add position management and capital management rules, such as adjusting positions based on trend strength or profitability, setting overall stop-loss lines, etc., to further control strategy risks.

The Marina Parfenova School Project Bot is a quantitative trading strategy based on moving averages and Bollinger Bands. It attempts to profit by capturing market trends while controlling drawdowns through Bollinger Band stop-loss lines. The strategy logic is simple and straightforward, with a wide range of applications, and parameters can be flexibly adjusted according to market characteristics. However, in practical application, attention still needs to be paid to issues such as sideways markets, extreme conditions, parameter optimization, etc., and further refinement of capital and position management rules is necessary. Overall, this strategy can serve as a basic quantitative trading framework, which can be continuously optimized and improved upon to achieve more robust trading results.
