Hello SC, Preface - ID20.SG1 = 20 Volume SMA - Formula below means alert if "Volume is more than 20SMA and Average of previous 3 candles OR Volume more than previous candle which fulfills the condition I just said)" - Formula: =OR( AND(V > ID20.SG1, V >= 1.5 * AVERAGE(V[-1], V[-2], V[-3])), AND(V > V[-1], V[-1] > ID20.SG1[-1], V[-1] >= 1.5 * AVERAGE(V[-2], V[-3], V[-4])) ) - Logged output = OR( AND(13748 > 12664.1, 13748 >= 1.5 * AVERAGE(12022, 6798, 7862)), AND(13748 > 12022, 12022 > 12307.95, 12022 >= 1.5 * AVERAGE(6798, 7862, 6482)) ) Issue - Alert works - However, it is supposed to work when Volume > 20SMA. Numbers-wise, it's correct - Visually, volume looks lower than 20SMA which is confusing Chart Region Settings - Interactive Scale Range - Scale Range: Automatic Indicator's Scale Settings - Default (I.e Scale Range: Automatic Zero-Based, Scale Type: Linear) Any explanation why this happens? |

We need to see the entire chart, particularly so we can see the right side scale for that region. If you supply an image, please follow these instructions: Support Board Posting Information: Attaching or Posting a Screenshot/Image (Optional) You mention that the one study scale is set to "Automatic Zero-Based", we assume this is the Volume. What is the Moving Average scale type set to? For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

The MA is set to Automatic. I have uploaded the entire Chart itself: https://www.sierrachart.com/image.php?Image=175441392315.png |

This formula: =OR( AND(V > ID20.SG1, V >= 1.5 * AVERAGE(V[-1], V[-2], V[-3])), AND(V > V[-1], V[-1] > ID20.SG1[-1], V[-1] >= 1.5 * AVERAGE(V[-2], V[-3], V[-4])) ) Does not mean ""Volume is more than 20SMA and Average of previous 3 candles OR Volume more than previous candle which fulfills the condition I just said)". You have two ANDs, which are nested into an OR, which does separate out the two conditions, so either AND() condition could be true. But the second AND() condition checks that the volume of the current bar is greater than the volume of the previous bar AND the volume of the previous bar is greater than ID20.SG1, AND the volume of the previous bar is greater than or equal to 1.5 times the average of the volumes from the bars 2, 3 and 4 back from the current bar. Make sure your conditions are actually being met, as there is no condition in what you have that checks just that the SMA is greater than the volume of a bar.

1st AND = Volume is more than 20SMA and Average of previous 3 candles AND(V > ID20.SG1, V >= 1.5 * AVERAGE(V[-1], V[-2], V[-3]))
2nd AND = Volume is more than prior Candle. Prior candle's volume is more than 20SMA at the prior candle and Average of previous 3 candles before that prior candle AND(V > V[-1], V[-1] > ID20.SG1[-1], V[-1] >= 1.5 * AVERAGE(V[-2], V[-3], V[-4])
Enclosing OR = So in either case, if I do see a colored bar in the volume histogram, either that bar or the previous bar must be above the 20SMA right? _________________ If you look at the chart uploaded where I have arrowed out some colored bars, none of them fulfills this Enclosing OR = So in either case, if I do see a colored bar in the volume histogram, either that bar or the previous bar must be above the 20SMA right?
I meant volume of bar has to be above SMA not SMA above volume of bar, hence why I am confused when I mentioned "Visually, volume looks lower than 20SMA ..." : there is no condition in what you have that checks just that the SMA is greater than the volume of a bar.

We understand what you are referring to now, sorry it took us a bit. Please get us that chart so we can take a look, as there must be some reason for what is occurring.

No worries, here is the chartbook.

The problem was with the order of the calculations. Keep in mind that, in general, the order of the items in the Studies to Graph is the order in which the studies are calculated, going from top to bottom. Therefore, you need to have the studies in this order: - Volume - 20SMA - Volume Spike 1.5 - Volume Spike 1.8 - Volume Spike 2.0 As each of these depends on the ones before it, and the Color Bars need to color correctly, which also follows the same order, so they need to be in the order they are (which is how you had them).

Thank you, this worked! However, I still don't understand the logic behind it So... - We have a order precedence as you mentioned - But how does Color Bars use that order precedence when it has been properly accounted for (or so I thought) with our Formulas, brackets, etc in the "Alerts" tab Also, sorry for the trouble, is there documentation to this, I can't seem to find with the keywords "Calculation order" in SC's search bar |

The real issue was the 20SMA with regards to the Volume. Those two were the ones that were out of order and was causing the issue. Although the "Color Bar Based on Alert Condition" would normally have the same issue, the precedence for that specific study is set to low, so it will run after other studies.
