Overview

This is a simple quantitative strategy that uses the Money Flow Index to identify “big sharks” in the market. It is suitable for the 5-minute timeframe and is mainly used for cryptocurrency trading.

Strategy Principle

The strategy uses a 3-period Money Flow Index with an overbought level set at 100 and an oversold level set at 0. The strategy waits for the Money Flow Index to reach overbought levels, indicating the presence of “big sharks” in the market. If price holds up on the first two overbought occurrences of the Money Flow Index for the day, it is considered a bullish entry signal.

A long entry is taken when Money Flow Index = 100 and next candle is a bullish candle with short wicks. The stop loss is set below the low of the trading day and profit is taken within 60 minutes after entry.

The logic above can be used in a mirrored fashion to take short entries as well.

Advantages of the Strategy

Using Money Flow Index can effectively identify accumulation behavior by “big sharks” in the market, stocks with continuation potential.
Candlestick filters help confirm stronger breakouts, avoiding many false breaks.
The SMA filter avoids buying into declining trends, effectively reducing risk.
60-minute time-based exits quickly lock in profits, reducing drawdowns.

Risks of the Strategy

Money Flow Index may generate false signals, leading to unnecessary losses. Parameters can be adjusted or additional filters added.
60-minute exits may be too aggressive for high volatility stocks. Profit taking time or moving stop loss can be optimized.
Major macro events are not considered which can impact markets. Strategy should be paused until markets stabilize.

Enhancement Opportunities

Test different parameter combinations like MFI length, SMA periods etc.
Add other indicators like Bollinger Bands, RSI to improve signal accuracy.
Test widening stops to allow larger profit targets.
Develop versions for other timeframes like 15 or 30 minutes based on same principles.

Conclusion

The strategy is simple and easy to understand, aligning with the classic approach of tracking “big sharks”. Key overbought/oversold levels combined with candlestick filters remove noise. The SMA filter further enhances robustness.

The 60-minute timeframe allows fast profits but also introduces higher risk. Overall an insightful strategy template for exploration and optimization, providing a blueprint for systematic development.

// * I'm using a SMA filter to avoid buying when the price is declining. Time frame was better at 15 min according to my test.

// 1 - Apply the 3 period Money Flow Index indicator to the 5 minute chart, using 0 and 100 as our oversold and overbought boundaries
// 2 - Wait for the MFI to reach overbought levels, that indicates the presence of "big sharks" in the market. Price needs to hold up
// the first two MFI overbought occurrences of the day to be considered as a bullish entry signal.*
// 3 - We buy when the MFI = 100 and the next candle is a bullish candle with short wicks.
// 4 - We place our Stop Loss below the low of the trading day and we Take Profit during the first 60 minutes after taking the trade. 

// The logic above can be used in a mirrored fashion to take short entries, this is a custom parameter that can be modified from
// the strategy Inputs panel.
