I am using an alert formula to detect when the low of the current candle is within a certain distance above a critical level. The logic works correctly with studies such as VWAP, VPOC, etc., but fails completely when using the Daily OHLC study current day low (SG3[0]). My alert condition is: AND( abs(L[0]-ID15.SG3[0]) < ID60.SG4[-1]*ticksize, L[0] >= ID15.SG3[0] ) Where: ID15 = Daily OHLC study SG3 = Low ID60.SG4[-1]*ticksize = proximity threshold My intention is to detect when the current bar low is within a defined distance above the current day's developing low. Observed behavior: The condition works correctly if I replace ID15.SG3[0] with: VWAP VPOC and other constant or intraday-updating reference levels However, using ID15.SG3[0] (current day low), the alert triggers sometimes, sometimes not, even when the candle low is clearly within the threshold. Visually, SG3[0] displays correctly on the chart and matches the current session low. Date Time Of Last Edit: 2026-02-20 15:13:14

We do not know what may be occurring. We do not see anything specific in the formula that would cause an issue. You would have to check the values at each location where you think you should have the alert but are not getting it. You can get the values from the Tool Values Window. But we also recommend using the "Spreadsheet Formula" study, which, despite its name, uses the Alert Syntax. So you can enter pieces of your condition exactly as you have them and then build up, or use multiple copies in order to determine why you are not getting what you are expecting.
