A “Bad Tick” is the event when a market price jumps to another level of market range(to an extreme point) and comes back to the normal price immediately.

There are mainly 2 reasons which cause such an event.

1. Price Feed Error

There may have been error on your broker’s side or Liquidity Provider’s side. As in, they have accidentally sent a false market price data.

In this case, brokers often restore all accidentally closed orders and correct any numbers that went wrong.

2. Intentional “Stop Hunting”

It’s very difficult to define, but “Stop Hunting” do exist as far as we see and hear by market experts.

“Stop Hunting” is when the bad tick is caused intentionally, in order to cause losses on traders’ side, thus brokers making profit.

In this case, these brokers often refuse to correct any numbers of restore closed positions.
