If Candles closes below at least 4 Fibonacci line then trend is down if Candles closes are above minimum 4 Fibonacci line the trend is up.
Fibonacci line act as support for Uptrend market similarly same lines act as resistance for downtrend market.
Before new trend start all lines shrink together and looks like single thick line.
And When trend almost matures then all lines are expanded and they have spaces between them.
Hope it will help new trader. This study is not for Buy and Sell.
