Hello, I am currently using Study Overlay to do a Moving Average Crossover. The source chart is a 60 minute chart and destination chart is a 10 minute chart. What I want is that when the moving average crosses over on 60 minute chart, I should trade based on 10 minute chart. The logic is as soon as the moving average crossover happens on the 60 minute chart, I should be able to trade on the 10 minute chart on the bar close of the 10 minute chart. The code works fine when I back-test the data. However on live trading the trade is only automatically executed when 60 minute bar closes. So if the crossover happens at 10:13 AM for example, the trade should execute on 10 minute bar close at 10:20 AM. This works fine in back-testing. However in live trading the trade executed at 11:00 AM instead, which is the 60 minute bar close. Not sure why this is happening. The chart order: Chart 1: 60 minute chart Chart 2: 10 minute chart Study Overlay Study on 10 minute chart referencing 60 minute chart. Then I am referencing the moving averages through my code from the Study Overlay. The following code has been added to my coded study: sc.CalculationPrecedence = LOW_PREC_LEVEL sc.GetStudyArrayUsingID(Input_ID1.GetStudyID(), Input_ID1.GetSubgraphIndex(), Arr_ID1); sc.GetStudyArrayUsingID(Input_ID2.GetStudyID(), Input_ID2.GetSubgraphIndex(), Arr_ID2); Output_ID1[cB] = Arr_ID1[cB]; Output_ID2[cB] = Arr_ID2[cB]; An example of Buy Entry Condition on the 10 minute chart: (Output_ID1 => Moving Average 1 and Output_ID2 => Moving Average 2) if ((Output_ID1[sc.Index - 1] < Output_ID2[sc.Index - 1]) && (Output_ID1[sc.Index] > Output_ID2[sc.Index]) && (sc.GetBarHasClosedStatus(sc.Index) == BHCS_BAR_HAS_CLOSED)) BuyToOpen = 1; s_SCPositionData PositionData; sc.GetTradePosition(PositionData); if ((BuyToOpen == 1) && (PositionData.PositionQuantity == 0)) sc.BuyEntry(NewOrder); Not sure why the behavior in back-testing is done correctly and not working in Live Trading (CQG WebAPI).

The first thing you should do is study carefully the Study/Price Overlay study and its Inputs: Study/Price Overlay Study Make sure the Inputs are set as you require. And when a chart is updating live, make sure the Study/Price Overlay is displaying the data that is needed, at the last chart bar. Is that the case? If so, we would not expect a problem like this.

Thank you for your reply. I think I figured out the problem and now hope you can help with a solution. Problem: The crossover of moving averages happens at the end of the 60 minute bar (reference chart: 60min), even though I am trading on the 10 minute bar. When I overlay the 60 minute moving averages on the 10 minute chart, it looks like the crossover happens around the 30 minute mark in the 60 minute bar. However by doing a complete chartbook replay, I notice that only after the 60 minute bar is complete does the crossover reflect on the 10 minute charts 30 minutes into the bar (instead of at 60 minutes). What I want to do is calculate this true crossover on the 10 minute chart i.e. at the 30 minute mark. Is there anyway I can do that? Hope this makes sense. |

It is hard for us to fully understand this from our perspective because we do not have your charts and studies, but check these two inputs: Study/Price Overlay Study: Data Copy Mode Study/Price Overlay Study: Bar Time Matching Method Sierra Chart Support - Engineering Level Your definitive source for support.

I am attaching an example of a 30 minute chart crossover on a 3 minute chart. After the crossover on the 30 minute bar is done at 10:00 AM, it shows up on the 3 minute chart at 9:45 AM. Is there anyway to calculate the 30 minute bar value on the 3 minute chart to reflect crossover at 9:45 AM in real-time instead of waiting for 30 minute bar close? I am attaching the Study Overlay settings and snapshot of the example |

Thank you. Setting to containing match worked. I noticed another issue though... I get different results when I replay all charts (source and destination charts) as compared to only destination chart (the traded chart) when I do automated backtesting. Do you know why? I would assume after changing to "containing match" the results shouldn't be different anymore. |
