Hi 

 

Thanks for pointing out these chart spikes. They were reported to our chart specialist on the technical desk for which these have been addressed. 

 

Should you notice any spikes in the future on the ProRealTime platform all you need to do is go to 'Help' and then select 'Technical support' and then in the dialogue box you can mention there is a chart spike and have it so that screenshots will be added. Once you select send report that goes to us directly and we will be able to get these anomalies corrected.

 

I do hope that helps and thanks again for bringing this to our attention!

Hi all, I noticed that the Top40 spiked by about 789 points at 16:52:06, a high of 47468 and closed back to 46679. Maybe I do not understand it properly, hence my question. If it is possible that the top40 can make such a huge jump in 1 second and return to its previous position, what would the effect be if I had (and fortunately I did not), limits or stops set within that range? Would it have triggered and closed my positions? Afterwards I checked the prices of approximately 25 of the top40 constituents (the largest contributors) and can not see any huge moves in their prices that could have triggered such a spike...? If it was not the constituents that caused the spike then what was it? Please help....

Hi 

 

The spike you see in the Top40 cash chart does indeed look to be erroneous. However after speaking to the Indices desk the spike reported was actually caused by the futures contract spiking and so this would mean this was caused by actual trading. 

 

I hope that helps!
