Hi - I'm using the OEC live feed into Sierra Charts and using the number bars study to show me a footprint. The issue is that the Sierra number bars are not accurately displaying the proper ticks and volume that my OEC is giving it. For example, I'm trading the GCLJ4 crude light contract and the low of day on the number bars at 97.57 shows 45x10 i.e. 55 contracts traded. However, my OEC feed (through my trading platform) only shows 20 traded at the 97.57 low. I have checked this with other traders and there were only 20 contracts traded at that low. Any idea what to do to fix the Sierra Charts/number bars? Thanks Simon |

There are only two recommendations we have: Make sure you have a tick by tick data configuration: https://www.sierrachart.com/index.php?l=doc/doc_TickbyTickDataConfiguration.php If that does not help use the Sierra Chart Real-time and Historical Exchange Data Feed: https://www.sierrachart.com/index.php?l=doc/SierraChartRealTimeFuturesStockDataFeed.php Sierra Chart Support - Engineering Level Your definitive source for support.

Thanks for that. I didn't have it set to tick by tick data, which I changed, then reloaded my chart data but it didn't work - still bad ticks showing incorrect volume. I then tried to follow the instructions to activate the Sierra real time and historical feed but had to give up as I got TOTALLY lost, concluding that it wanted me to pay for a feed that is supposed to be free (I'm on the trial trying to work out if Sierra number bars are an adequate alternative to Market Delta Footprint). Is there an idiot guide to getting the Sierra fee to work? Thanks Simon |

The Sierra Chart data feed is a paid data feed and it costs 35 USD a month plus exchange fees. Just because there is a free trial does not mean everything Sierra Chart provides access to is free. You should not make that assumption. The free trial has limitations. Take our advice, put no reliance on the OEC data feed for what you want. Use the Sierra Chart data feed and pay for it. You will make things much easier for yourself. We will get the data feed set up for you, please add about 25 USD to your account here: https://www.sierrachart.com/usercp.php?page=AddAccountCredit Respond back when the payment is made.

I'm afraid I have to disagree with you on the reliability of the OEC feed. I know many traders who use the OEC feed and who will vouch for its accuracy tick for tick when lined up against IQFeed (arguably one of the better feeds on the market). Thanks again for your help, but my conclusion to my test is that Sierra Charts number bars are no comparison to the Market Delta footprint. Best, Simon |

You can believe whatever you want. Sierra Chart Numbers Bars do work perfectly if there is a good data feed. Also, many on this board will say the OEC feed is substandard compared to good data feeds when it comes to bid volume and ask volume and even total trade volume.

We did a comparison with OEC data feed and the Sierra Chart data feed and the results are below. 2014-03-17 ESM4 Total volume recorded from trades during the time 16:15 through 16:14:59 US Eastern time. Sierra Chart data feed: 1342457 OEC data feed from real-time data recording: 1320779 Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

We had a look at the OEC historical data that we have, for the apparent time in question and we do see 20 contracts traded at that price: http://www.sierrachart.com/image.php?l=1395104083374.png This means that you did not re-download the data after switching to 1 Tick, according to the instructions here: https://www.sierrachart.com/index.php?l=doc/doc_TickbyTickDataConfiguration.php There really is no other possibility of getting a different result, unless you changed the Volume at Price multiplier in Chart Settings.

Ah yes, thanks! I forced it to delete the data and reload again and now it's showing 20 traded at that 97.57 low. I'll have another crack at it in tomorrow's session. Cheers Simon |

AnimalHungry, A few years ago I used an old version of the Market Delta Footprint that worked in the OEC Trader. I have no doubt that the OEC data is good in the OEC Trader or the Market Delta Trader that works with OEC, but you should keep in mind that OEC has a financial relationship with Market Delta (it's not free). They have every incentive to make sure the data is accurate. On the other hand I don't know of any financial relationship between Sierra Chart and OEC. The bid/ask data is OK when the markets are slow, but when the volatility picks up the bid and ask gets mixed up or all the volume will go to the bid or ask. Why this is? One side blames the other. I just follow the simple rule: you get what you pay for. The historical data is good, but the real time data is not. Why - another mystery of life. Good Trading, WT |

Why this is? It is no mystery to us. The bid and ask price data feed from OEC is like a separate data feed and it is not always completely in sync with the tick by tick feed. So trying to use it to identify whether a trade occurred at the bid or ask is not entirely accurate.Whereas the Sierra Chart Exchange Data Feed uses the "aggressor" field from the CME to make this determination.

Very interesting. I didn't know any of that and now makes what I'm seeing using OEC data into Sierra Chart all make sense. Thanks! Simon |
