DislikedI give GPT a hard disagree on this. Volumes increase at session open, however the significance of the fix is that IV figures are published, which all vol models calibrate against. Try it. If I’m wrong, shoot me! Also yes IV <> Range but they’re so close as to be virtual twins. The more accurate your forecast the better you know what’s ’normal bounce’ for a range vs true breakout. it’s good to check these things but be careful — it’s been fed on retail gubbins not institutional notes. It copes very well with models and maths because it can source...Ignored
In any case, I'm not exactly sure how I would implement such a filter but I also asked AI and it says the following:
"To code an implied volatility (IV) filter for an Opening Range Breakout (ORB) strategy, you need to first acquire historical IV data and then implement conditional logic based on that data, using a library like yfinance to fetch the data for the filtering logic. A common approach is to use the Average True Range (ATR) as a proxy for historical volatility if real-time IV data for options is unavailable or too complex to integrate."
Perhaps it's an overkill and ADR is just as fine as a dynamic volatility filter, hmm.
Asking AI again for what kind of volatility regime filters "Institutional traders" use, I get the following answer:
"Institutional traders primarily use sophisticated, volume-based filters and market context tools, rather than relying solely on typical retail indicators. Key filters and tools include Volume-Weighted Average Price (VWAP), Average True Range (ATR), implied volatility (VIX), and proprietary order flow analysis systems"
So yes, VIX is mentioned here as one possible candidate. The other ones are backward looking like ADR.
Regrading "fix" times, I think I misunderstood, and that's what you mean.
"In Forex, "fix" refers to specific daily times, especially the 4 PM London time (GMT), when major banks and institutions set benchmark currency rates by averaging trades over a short window (like 60 seconds) for large corporate and fund valuations, creating concentrated trading volume and potential volatility. Other significant fixes include the WM/Reuters Fix (12 PM & 4 PM GMT), ECB Fix (2:15 PM CET), and Tokyo Fix. These "fixes" provide crucial reference points for derivatives, reporting, and portfolio management in the 24/7 currency market."
Yes, I've tried the 4:00 PM breakout time as a reference point for GPB/USD in the past, but it didn't really yield better results for me compared to the London Open at 8:00 AM. Also, since I only want to trade intraday and don't want to hold positions overnight, the later in the day I enter on a breakout entry the less likely to still reach an adequate profit target. In my experience/observation, not only for indices, gold, or major forex pairs, the expected average daily range (of which I want to capture as much as possible before the day ends) often seems to be reached by mid-afternoon my time.
