orders filling at prices that didn't trade?

Can this happen or is this bad demo data? You can see my order was filled below the low of the candle.

 

Bad demo data.

 

%%
Easy to explain;
most intraday charts are filled with errors.
And figure the market makers[real time , differs from demo] charts are faster than yours\ besides your chart is downtrending\so that happens more like that direction.................................................................................

 

Trades of less than 100 shares won't show up on the chart. You can see these trades by looking at the level II data but the price shown on the chart won't update.

 

It could be an issues with the data feed
They price will get updated after a certain time
You can compare the price on other brokers or on Trading View .

 

what? It didn't appear on DOM either.

Most likely.
And i've seen price trade thru on my resting orders[SCHW]+ NOT get filled real time /LOL
BUT that's on ''orders section'' . IT actually will have filled , in my account, but just not show up in my SCHW order section................................................ Common repeating patterns.

 

Can happen for sure with slippage during highly volatile events. I would be keeping out of any high news events thats when it most likely occurs
