Tick
A tick is the minimum price step of a symbol. MetaTrader 5 calls that step the tick size.
Explanation
Market Watch defines tick size as the minimum price change, and tick value as the cost of one such step. Spread and the stop-level distance are shown in points, which are the platform's price units and can be finer than a pip. A new tick is also what re-triggers a stop loss or take profit if the first attempt to close cannot be executed. Tick size is a symbol setting. It is not the same number on every pair.
