I do not know in which forum should ask this, please could you explain me the meaning of my screenshot, often i see huge transactions in the post market, with gigantic candles, who is doing what? I know that post market is illiquid,and sharks navigate in darks pools, but why i see these huge candles, who is buying post market, only institutions? I do not get it looks as something sneaky is going on, is possible using the post market as an indicator of were smart money is going? And the small red candle is because the opening post market price from the candle was really low and then matched in one hour the closing?
That looks like a data glitch. Anyone else have a similar 1h chart to confirm on QQQ? The NQ did not have that behavior.
An interesting chart you have. Would you mind saying a few words about it, besides that last (Predictive?) bar? qqq chart here with evening session ... https://www.elitetrader.com/et/threads/charts-for-no-reason.344272/page-21#post-5572027
That looks like a trade that should have been filtered for one of many different reasons. For example, dark pool trades are often filtered out because they can trade thru NBBO and create those spikes you sometimes see. The exact combinations of trade conditions that cause trades to be filtered sometimes vary depending on your data provider. There is also an auction process that happens at the close or 1 minute after the close. These are for order types sent to exchanges designed to trade on the closing price. If there are imbalances that too can create wacky end of day trading with high volume.
That. Free data many times is crap data. Not that paid for data doesn't have that happen sometimes too. Just way less ooooften.
Hourly chart, is one of the charts I refer every day, in the specific here I use telechart also known as TC2000, outside the after hour highlighted part, I have two lines super correlated that are basically SP500 and QQQ(the fact there is also the QQQ as candles is just a coincidence in this case), 10,20 exp moving average, 65 ma, vwap, volume, I use the hourly to monitor where day and swing traders are converging during working hours
please I do not get this data glitch, to my knowledge is when the market is halted, I do not get what your graph mean, also i pay 40 dollar per month to use this service, so is not free( but maybe I pay for the scan, visualization possibilities, while accurate data may be out from the platinum tc2000 package)
Along the bottom is the time axis - which shows up to the time I posted 8:52pm EDT no spike down of any kind. If spike hasn't disappear from your chart by now I would advise by email, or whatever way you can, the TC folks to correct it.
If the tick data is stored on your machine locally, you can clear out the bad data and redownload the historical data. That should eliminate the error.
