Hi Thanks for taking the time to read and help me come up to speed on Sierra Charts. I am mainly interested in the spreadsheet functionality and using indicators that exists and some of my own logic in the same row. 1. I want to add my own custom functions that are based on the cells in the same row how can I do that? I put the formula in row 3 and thought that it was suppose to populate the rest of the column automatically when data comes in. How do I do this? 2. How do I do play back in the spreadsheet? I see the chart moving but I don't see the data replaying in the spreadsheet. 3. For the normally these indicators depend on previous rows, how do you deal with the in the first place. For example prev_close - curr_close for the first piece indicator row in the spreadsheet? |

1) With the spreadsheet studies, only columns K-Z...BR will auto-populate from row 3, depending on the Number of Formula Columns setting (16 to 60). These should auto-populate in the New Spreadsheets version, but in the Old Spreadsheets version you can force it to recalculate by going to Chart >> Recalculate. 2) Since the spreadsheet study is added to the chart, scroll the chart into the past, and go to Chart >> Replay Chart. If the spreadsheet data is not following the chart data, you may be looking at the wrong sheet#. By default, the chart# will output to its respective sheet#. 3) Each spreadsheet row is a chart bar. The current bar is in row 3; previous bars are rows below. For the previous bar, reference row 4 in your row 3 formula. |

1. Spreadsheets do not support custom functions. However, they do support your own custom formulas. Carefully follow through the step-by-step instructions on this page here: https://www.sierrachart.com/index.php?page=doc/doc_StudiesSystemsAlerts.php 2. Also carefully follow through the step-by-step instructions here: https://www.sierrachart.com/index.php?page=doc/doc_StudiesSystemsAlerts.php 3. For the last row outputted to the Spreadsheet, this can be a problem. However, you can solve it by checking for 0 in the previous row and then have the formula return 0 in this case.

I think you may have answered this in #3 but just to clarify. I am trying to do the following I am trying to do a custom formula. For example even though you already have this study. I would like to do SMA for 4 time periods. in my custom formula in row 3 how would I write that since I need 4 time period before the calculation actually can happen. Assuming ID0.SG4 is LastPrice Row Formula 3 =(ID0.SG4@3+???)/4.0 4 =(ID0.SG4@3+ID0.SG4@4 + ???)/4.0 5 =(ID0.SG4@3+ID0.SG4@4 + ID0.SG4@5 + ???)/4.0 5 =(ID0.SG4@3+ID0.SG4@4 + ID0.SG4@5 + + ID0.SG4@6)/4.0 <-- This can actually calculate now. How do I represent this in row 3? since I can't go ID0.SG4@2, ID0.SG4@1, ID0.SG4@0? Even simpler example is difference between current and last price. How do I do that in custom formula in row 3? Thanks again |

This formula in row 3 of a Formula Column will recreate an SMA of the Last price: =AVERAGE(OFFSET(ID0.SG4@3,0,0,$K$1,1)) or =AVERAGE(OFFSET(E3,0,0,$K$1,1)) where K1 is the length. If you want to do 4 SMAs of an SMA, you'll need 4 Formula Columns, the first referencing column E, and the others each referencing the column to the left. This formula in row 3 will give the difference between current price and previous Last price: =ID0.SG4@3-ID0.SG4@4 or =E3-E4 |

Great, thx for the clarity. I understand that the first value is really for row 6 in row 3 for the belo=w formula. How would I reference that in my next column? So if column P3 =AVERAGE(OFFSET(E3,0,0,4,1)) Whats is column's Q3 formula since there is no cell to reference 4 back? =P0? |

For an SMA of P3[-1], in Q3: =AVERAGE(OFFSET(P4,0,0,4,1)) If you want an SMA of E3+ the previous P4, you'll need to use another Formula Column (Q3) to combine the values: =E3+P4 then in R3: =AVERAGE(OFFSET(Q3,0,0,4,1)) The spreadsheet array is in descending order; previous bars are in rows below row 3.
