Zero plus tick refers to a transaction made at the same price as a preceding trade, but at a price higher than two transactions previous. Also know as zero up tick.

Written descriptions of zero plus ticks are far more complicated than the actual concept. As an example of a zero plus tick, if trades are executed at 52, then 53 and then 53 again - then the last trade at 53 was a zero plus tick.

One of the biggest disadvantages of speculating in the stock market is the rule that prevents shorting shares on a downtick. Share traders are not able to short a stock during a downtick or zero downtick - only after an up-tick of price in the share. Having to wait for the market to increase is may be costly for those looking to profit from a decline in price. Such restrictions on shorting and profiting from asset's decline do not exist in the FX Market.
