How a candlestick is formed?
Ex:
Current price is 100
Sell order available at 101, 102, 105
Buy order available at 99, 98, 96, 95
Now the price will move up or down?
Depends on whether Buyer increases bid price or Seller reduces offer price.
For example if buyer bids for 100.5 and seller to offers at 100.5 trade will take place and 100.5 will become Last Traded Price (LTP).
If neither happens there will be no trade taking place and price will stay as is.
Thank you
