High/Severe Slippage

I experienced this issue, not once but twice. At 1st, my SL position got hit even though it was too far, approximately 1:3. When I checked the chart, a very long wick was created in 1min tf. And then I compare it to other platforms, especially TradingView but it hasn't shown any long wick. I didn't mind my 1st encounter because I thought it was a graphical error or due to low volume. But the 2nd time, the same scenario I experienced. And when I checked their chart, It didn't show any long wick created. Then I compare it again to other platforms. I was confused why my SL got hit even though the chart didn't show a long wick candle that causes my SL to triggered. And when I review the history of all market prices of FPG and compared to other platforms, some of their candlesticks got a very long wick. I was so disappointed with this broker. I lost my capital without justice. Please remind them to fix this scam activity. This is so alarming. Please see attached file for proof. Thank you!
