Sorry I should clarify - spread is completely the wrong word.
The *difference* between the high and low of day is the number I hypothetically have. However, I would not know the HOD or LOD, just the difference between them.
i.e. today's stock price is $3. The tool I have would predict tomorrow's HOD LOD difference is $2. Tomorrow's actual stock price trades as such:
HOD - $6
LOD - $4
You don't know *when* the LOD will happen. You just know that at some point the difference b/t HOD and LOD for that day is $2. For the record, this does not have to be for penny stocks. It would actually be more likely for high volume stocks >$5, with good volatility.
I'm developing software that creates technicals. This 'difference' function just happens to be one of the easier things to predict about tomorrow's price. This is in no way confirmed yet, I am just playing around with the software as I go along.. will update you on progress as I move on.
This is another story, yes, spread was a wrong word, ok, you can predict the difference between HOD and LOD, you gave the HOD - $6 and LOD - $4 example, but, it can also be HOD - $5 and LOD - $3, or HOD - $4.5 and LOD - $2.5, or HOD - $5.5 and LOD - $3.5 or am I wrong?
If your software can predict the difference between the HOD and the LOD but, also the LOD and the HOD, that would be a great tool, but, if only the first hypothesis, I still don't see any practice advantage.
