[SHORT ONLY] Consecutive Bars Above MA Strategy

█ STRATEGY DESCRIPTION
The "Consecutive Bars Above MA Strategy" is a contrarian trading system aimed at exploiting overextended bullish moves in stocks and ETFs. It monitors the number of consecutive bars that close above a chosen short-term moving average (which can be either a Simple Moving Average or an Exponential Moving Average). Once the count reaches a preset threshold and the current bar’s close exceeds the previous bar’s high within a designated trading window, a short entry is initiated. An optional EMA filter further refines entries by requiring that the current close is below the 200-period EMA, helping to ensure that trades are taken in a bearish environment.

█ HOW ARE THE CONSECUTIVE BULLISH COUNTS CALCULATED?
The strategy utilizes a counter variable, `bullCount`, to track consecutive bullish bars based on their relation to the short-term moving average. Here’s how the count is determined:

1. Initialize the Counter
   The counter is initialized at the start:
   
   Pine Script®
2. Bullish Bar Detection
   For each bar, if the close is above the selected moving average (either SMA or EMA, based on user input), the counter is incremented:
   
   Pine Script®
3. Reset on Non-Bullish Condition
   If the close does not exceed the moving average, the counter resets to zero, indicating a break in the consecutive bullish streak.
   

█ SIGNAL GENERATION

1. SHORT ENTRY
A short signal is generated when:

• The number of consecutive bullish bars (i.e., bars closing above the short-term MA) meets or exceeds the defined threshold (default: 3).
  
• The current bar’s close is higher than the previous bar’s high.
  
• The signal occurs within the specified trading window (between Start Time and End Time).
  
• Additionally, if the EMA filter is enabled, the entry is only executed when the current close is below the 200-period EMA.

2. EXIT CONDITION

• An exit signal is triggered when the current close falls below the previous bar’s low, prompting the strategy to close the short position.

█ ADDITIONAL SETTINGS

• Threshold: The number of consecutive bullish bars required to trigger a short entry (default is 3).
  
• Trading Window: The Start Time and End Time inputs define when the strategy is active.
  
• Moving Average Settings: Choose between SMA and EMA, and set the MA length (default is 5), which is used to assess each bar’s bullish condition.
  
• EMA Filter (Optional): When enabled, this filter requires that the current close is below the 200-period EMA, supporting entries in a downtrend.
  

█ PERFORMANCE OVERVIEW

• This strategy is designed for stocks and ETFs and can be applied across various timeframes.
  
• It seeks to capture mean reversion by shorting after a series of bullish bars suggests an overextended move.
  
• The approach employs a contrarian short entry by waiting for a breakout (close > previous high) following consecutive bullish bars.
  
• The adjustable moving average settings and optional EMA filter allow for further optimization based on market conditions.
  
• Comprehensive backtesting is recommended to fine-tune the threshold, moving average parameters, and filter settings for optimal performance.
