Ignored stop order led to lose 30 points

Price gaps was used as an excuse why stop order wasn’t triggered when the stock moved past the stop set by me. Take-profit order was triggered when the stock didn’t move past the point.The price of short order is 1423, but it is sold at 1420. What a ridiculous! I examined the quotation over three platform, without finding out price gaps in Candlestick chart. The following pictures say louder that my explanations.
