What is the meaning of nth candle exactly?

Algos, strategies, code

It has a very vague meaning. If I choose Entry condition as “nth candle” with:

  • High

  • Offset = -2

  • 5 min

Then what does this mean exactly? It means whenever we get 2 green candlesticks we will buy the shares?

What I’m trying to do is keep monitoring the candles every 5 mins. After any 2 red colored candles if a green appears then buy. How can I set this up?
