Best for 0dte/intraday trading on SPY with 1 minute chart
Strategy Concept
This strategy aims to identify potential reversal points in a price trend by combining momentum indicators (RSI and MFI), volume-weighted price (VWAP), and recent price action trends. It looks for conditions where the price is poised to change direction, either bouncing off a support level in a potential uptrend or falling from a resistance level in a potential downtrend.
By incorporating both price level analysis (support/resistance) and momentum indicators, the strategy seeks to increase the likelihood of identifying significant trend reversals, taking into consideration both recent price movements and the current price's position relative to historical highs and lows.

VWAP (Volume-Weighted Average Price)

• VWAP acts as a benchmark to determine the general market trend. It's an average price weighted by volume.
  
• A price above VWAP is often considered bullish, and a price below VWAP is seen as bearish.
  

MFI (Money Flow Index) and RSI (Relative Strength Index) Parameters

• MFI is a volume-weighted RSI, used to identify overbought (above 70) or oversold (below 30) conditions.
  
• RSI is a momentum indicator that measures the magnitude of recent price changes to identify overbought or oversold conditions, similar to MFI.
  
• The script uses standard overbought (70) and oversold (30) thresholds for both MFI and RSI.
  

Trend Check Function

• The function trendCheck analyzes the past pastBars candles to count how many were bullish (closing price higher than the opening price) and bearish.
  
• This function is used to assess the recent trend direction.
  

Support and Resistance Detection

• The script calculates the highest high (highestHigh) and lowest low (lowestLow) over the last lookbackSR (50) periods to identify potential support and resistance levels.
  
• isNearSupport and isNearResistance are conditions to check if the current price is within 0.08% of these identified levels, indicating proximity to support or resistance.
