Candlestick Patterns Backtester [Optimized]

Candlestick Patterns Backtester [Optimized]
What this is: This indicator is based on a really cool candlestick pattern backtester that I found (I'll update this later when I remember where I got it from or find the actual author). The original had this massive table showing win/loss ratios for a bunch of candlestick patterns, and according to the built-in backtester, it was actually profitable - which was pretty impressive.
The Problem: I played around with the original for a while but honestly wasn't really able to get it to work well at all for actual trading. It was still pretty cool to look at though! The main issues were:
It was just a big static table - hard to do anything useful with it
Couldn't send signals out to other strategies
The code was a monster - like 2,000+ lines of repetitive mess
What I Did: I completely refactored this thing and got it down from 2,000+ lines to just a few hundred lines. Much cleaner now! Here's what it does:
45+ Candlestick Patterns - All the classics are in there
Dynamic Filtering - Set your own requirements (minimum win rate, profit factor, total trades, etc.)
Flexible Logic - Choose AND/OR logic for your filters
Signal Generation - Creates actual buy/sell signals you can use with other strategies
Visual Badges - Shows pattern badges on chart when they meet your criteria
Active Patterns Table - Only shows patterns that are currently profitable based on your settings
Settings You Can Adjust:
Minimum win rate threshold
Minimum profit factor
Minimum number of trades required
Whether to use AND or OR logic for filtering
Colors, badge display, debug options
Reality Check: Trading these patterns really wasn't for me, but it was still a great learning experience. The backtesting results look good on paper, but as always, past performance doesn't guarantee future results. Use this as a research tool and educational resource more than anything else.
Credit: This is based on someone else's original work that I heavily modified and optimized. I'll update this description once I track down the original author to give proper credit where it's due.
This introduction captures your casual, honest tone while explaining the technical improvements you made and setting realistic expectations about the indicator's practical use.
