This is the jumping unit, or minimum variation required in the price of an asset traded on the automatic electronic market. Currently, the minimum variation in the SIBE depends on the price of the security in question: if the share is worth less than 50 euros, the share price will vary at least 0.01 euros; if it is more than 50, the tick will be 0.05 euros. For warrants and subscription rights, the tick is 0.01 euros, regardless of its price.
