HI,
A what time frame are you using DMI and where it works better?
Thanks
Most timeframes can benefit from it. DMI+/- is typically too noisy to be useful on their own but ADX provides a very good summary of market trend strength. Typically, it’s best if you have another, more rigorous method to determine trend direction (not DMI+/-) and use ADX only to confirm price momentum in that direction.
Your looking at the question the wrong way round. You should be asking which timeframe is most appropriate for your strategy (and only you can answer that question).
