OHLC for future

# OHLC for Futures

## Overview
This indicator helps traders identify key price levels from previous trading sessions. It displays the previous session's High, Low, Close, and the current session's Open as reference points on your chart.
I believe the day's opening price is crucial, while yesterday's opening price is irrelevant.

I haven't found a suitable OHLC indicator for futures trading, so I spent some time developing this one myself. As I'm currently migrating my trading from other platforms to TradingView, I need to create many indicators. Due to time constraints, there might be some bugs. If you encounter any issues or have suggestions for improvement, feel free to leave a comment or send me a private message.

## Key Features

## Common Trading Applications

**Support and Resistance**
Previous High and Low often act as key levels where price may reverse or pause.

**Opening Range**
The opening price frequently serves as a pivot point during the trading session.

**Gap Trading**
Compare current Open to previous Close to identify gap situations.

**Range Analysis**
Use previous day's range to assess current volatility and potential targets.

## Tips for Best Results
1. Set your chart timezone to match the exchange timezone

3. Verify session times match your futures contract specifications
