Below is a screenshot of the code in one of the example provided by SC. ( studies5.cpp -- BidAndAskPrices study) // Do data processing if ( (sc.Index < sc.ArraySize -1) || sc.IsReplayRunning()) { BidPrices[sc.Index] = sc.BaseData[SC_BID_PRICE][sc.Index]; AskPrices[sc.Index] = sc.BaseData[SC_ASK_PRICE][sc.Index]; } else { BidPrices[sc.Index] = sc.Bid; AskPrices[sc.Index] = sc.Ask; } I have 2 questions. 1. Can sc.Index be greater or equal sc.ArraySize? 2. How does sc.Index behave in real time with autoloop? Does it increase by one each time new bar is added? Date Time Of Last Edit: 2017-01-16 04:25:18

1. No this would make no sense at all. 2.

so the else condition from code above only happens when sc.index=sc.arraysize -1? What is the difference if i add equal sign inside if condition, ie if sc.index <=sc.arraysize-1 anx get rid of else section?

We do not understand the purpose of the question. You can certainly do what you want and obtain the result that you want. So effectively you just want to run this code always: BidPrices[sc.Index] = sc.BaseData[SC_BID_PRICE][sc.Index]; AskPrices[sc.Index] = sc.BaseData[SC_ASK_PRICE][sc.Index]; Sierra Chart Support - Engineering Level Your definitive source for support.

so the code under else is redundant here?

No. Refer to the documentation for the ACSIL members in question.

I have read the document. Simply my question is when the bar is in 1 tick level. Are the following two set of codes the same? 1. // Do data processing if ( (sc.Index < sc.ArraySize -1) || sc.IsReplayRunning()) { BidPrices[sc.Index] = sc.BaseData[SC_BID_PRICE][sc.Index]; AskPrices[sc.Index] = sc.BaseData[SC_ASK_PRICE][sc.Index]; } else { BidPrices[sc.Index] = sc.Bid; AskPrices[sc.Index] = sc.Ask; } 2. // Do data processing if ( (sc.Index <= sc.ArraySize -1) || sc.IsReplayRunning()) { BidPrices[sc.Index] = sc.BaseData[SC_BID_PRICE][sc.Index]; AskPrices[sc.Index] = sc.BaseData[SC_ASK_PRICE][sc.Index]; } |

No. The following always provide the most recent Bid and Ask price even when trading is not occurring. BidPrices[sc.Index] = sc.Bid;
AskPrices[sc.Index] = sc.Ask; Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.
