# Timeframe Interval Selection Fix

## Problem
When requesting a "4h" (4-hour) chart timeframe, TradingView was interpreting this as "4 minutes" instead of "4 hours", causing the wrong chart interval to be selected.

## Root Cause
The timeframe mapping was prioritizing hour notation ("4h", "4H") which TradingView was misinterpreting as minutes.

## Solution
Modified the timeframe mapping in `lib/tradingview-automation.ts` to:

### 1. Prioritize Minute Values
For hour-based timeframes, always try the minute equivalent first:
- "4h" now maps to: `["240", "240m", "4h", "4H"]`
- "1h" now maps to: `["60", "60m", "1h", "1H"]`
- "2h" now maps to: `["120", "120m", "2h", "2H"]`

### 2. Added More Hour Timeframes
Extended support for common trading timeframes:
- 2h = 120 minutes
- 6h = 360 minutes  
- 12h = 720 minutes

### 3. Enhanced Fallback Logic
Added a custom interval input fallback that:
- Converts timeframes to exact minutes (e.g., "4h" → "240")
- Looks for custom interval input fields
- Enters the minute value directly if standard selection fails

### 4. Improved Debugging
Added detailed logging to track:
- Which timeframe values are being tried
- The order of attempts
- Success/failure of each method

## Key Changes
```typescript
// OLD - Would try "4h" first (interpreted as 4 minutes)
'4h': ['4h', '4H', '240', '240m']

// NEW - Tries 240 minutes first (unambiguous)
'4h': ['240', '240m', '4h', '4H']
```

## Fallback Strategy
If regular timeframe selection fails:
1. Try keyboard shortcuts
2. **NEW**: Try custom interval input with exact minutes
3. Look for `input[data-name="text-input-field"]` and similar
4. Enter "240" for 4h, "60" for 1h, etc.

## Testing
The fix ensures that:
- ✅ "4h" request → 4-hour chart (not 4-minute)
- ✅ "1h" request → 1-hour chart (not 1-minute) 
- ✅ All common timeframes work correctly
- ✅ Fallback to custom input if needed
- ✅ Detailed logging for debugging

This fix addresses the core issue where timeframe selection was "stuck" at wrong intervals due to TradingView misinterpreting hour notation as minutes.
