Create a strategy comparison script.

Arguments

Parse

$ARGUMENTS

as: symbol followed by strategy names

```
$0
```
= symbol (e.g., SBIN, RELIANCE, NIFTY)
Remaining args = strategies to compare (e.g., ema-crossover rsi donchian)

If only a symbol is given with no strategies, compare: ema-crossover, rsi, donchian, supertrend. If "long-vs-short" is one of the strategies, compare longonly vs shortonly vs both for the first real strategy.

Instructions

Read the vectorbt-expert skill for reference patterns

Create a

.py

file in

D:\QuantFlow 3\Day17\backtesting\

named

{symbol}_strategy_comparison.py

The script must:
- Fetch data once via OpenAlgo
- Run each strategy on the same data
- Collect
```
pf.stats()
```
  from each into a side-by-side DataFrame
- Print the comparison table
- Plot overlaid equity curves for all strategies using Plotly
- Save comparison to CSV
Never use icons/emojis in code or logger output

Example Usage

/strategy-compare RELIANCE ema-crossover rsi donchian

/strategy-compare SBIN long-vs-short ema-crossover
