Finding the highest/lowest of the past X candles

[bravowhisky]

Is there a way to find the highest/lowest (high/low/open/close) value of past x number of candles?

Example, what do I find the highest close price of last 50 candles?

Or get High or Low from the candle in higher timeframe when possible
