## Introduction 
Cryptocurrency exchanges and DeFi platforms often encounter bugs or glitches which disrupt their smooth functioning.  At times, such disruption can lead to losses for traders and other short term investors. For example, a glitch that leads to panic in the market may cause prices of certain cryptocurrencies, especially the platform’s native token, to fall.  This article discusses the effect of a bug on Binance which resulted in a [pause of spot trading](https://www.gate.io/help/trade/trade/17244/about-spot-trading "pause of spot trading") for two hours.

## Binance Pauses Spot trading, what happened? 
On 24 March, a bug forced Binance crypto exchange to pause its spot trading service for two hours, something that created panic among its users. As such, no one would deposit, trade or withdraw from the spot trading section.

However, the crypto exchange’s CEO, Changpeng Zhao (CZ), constantly reminded its users that everything was under control and all the assets were safe. He even informed the users that the bug had affected the trailing stop.

CZ updated the users on Twitter. He said, “Initial analysis indicates the matching engine encountered a bug on a trailing stop order. Deposits & withdrawals are paused as a SOP (standard operating procedure).” He also reassured them that trading would resume within two hours.

What delayed the resumption of trading was the much time taken before identifying the nature of the glitch the exchange experienced. In fact, according to CZ, the platform identified the bug after 57 minutes. He also assured the users that the occurrence was unlikely to affect the price of cryptocurrencies.

He said, “When the biggest exchange halts trading, prices won’t move much. If it moves on smaller exchanges, when Binance comes back, our deeper orderbook will bring the price back, causing those guys to lose money. Traders know this.”

As per CZ’s assurance, spot trading resumed after about two hours from the time the exchange announced the bug and pausing of spot trading. Although spot trading continued at 2.00 UTC, the exchange paused trailing stop for some more hours.

## Understanding trailing stop loss
As mentioned above, trailing stop loss is an important aspect of risk management in spot trading. A trailing stop loss is a type of a stop loss order that maintains a fixed number of pips below or above a market order depending on whether it is a short trade or long trade. For example, with a long trade the stop loss moves up when the price is rising.

However, when the price goes against the market move the trailing stop loss will remain fixed. Traders can use pips or percentages when setting the stop loss, depending on what the trading platform allows.
