Truth about stop loss

Stop loss doesnt always work, and you cant always rely on it. I recently encountered an issue and after a talk with customer service i come to realise how big of a risk i am always in my trades.

In my case my stop loss did nothing when the price go away for more than 600 USDT at bitcoin. It ignored my stop loss and liquified my entire isolated position. Stop loss doesnt protect anyone from sudden moves of price action, esspecially if you are using high leverage(x125) like me. What happened at my case is, called as a "slippage". its a real thing all traders should know and be aware of before taking risk with their trades.
Here is the full answer regarding to my stop loss issue from customer service. It reveals all about stop loss and slippage;

"We are very sorry that your order was not fulfilled as you intended.
A market order is an order to quickly buy or sell at the best available current price. It needs liquidity to be filled, meaning that it is executed based on the limit orders that were previously placed on the order book. Unlike limit orders, where orders are placed on the order book, market orders are executed instantly at the current market price, meaning that you pay the fees as a market taker.
In case of your order, you put stop price as 62931 and the order was filled at 63,593.69, this is due to the fact that there were not enough buy/sell orders in the order book at the moment, which caused the slippage.
Please be aware that market orders are subject to slippage. For example, if there is not enough liquidity in a particular trading pair and there are not enough buy/sell orders, there may be a discrepancy between the current price and the execution price when buying/selling from the order book."

TL;DR
dont count on your stop loss orders.
