THE MONTHLY AND WEEKLY TIMEFRAMES MUST WORK TOGETHER
The monthly timeframe provides the bigger picture, while the weekly timeframe helps you understand the market's more recent behaviour.
For example, the monthly candle may show bullish expansion, but the weekly candle may be retracing.
That doesn't automatically mean the bullish idea has failed. The weekly movement could be a pullback within the larger range.
Always understand where price is trading before deciding whether to buy or sell.
