Heres a simple method that you can use to anticipate the trading range based on the previous days range. We use only Fibonacci numbers of 1.27 and 1.618.
First we identify the previous days range. In this example lets take the S&P 500 emini:
High: 1294
Low: 1281.50
Range: 12.5
Second, we take the
(Range x 1.27) + Previous Day Low
(12.5 x 1.27) + 1281.50 = 1297.375
This is our first estimated high.
To get the low:
High - (Range x 1.27)
1294 - (12.5 x 1.27) = 1278.125
This is our first estimated low.
Third: We use the same exact formula but replace 1.27 with 1.618.
High:
(Range x 1.618) + Previous Day Low
(12.5 x 1.618) + 1281.50 = 1301.725
This is our second estimated high.
Low:
High - (Range x 1.618)
1294 - (12.5 x 1.618) = 1273.775
This is our second estimated low.
Now we get two estimated ranges: 1297.375 - 1278.125 & 1301.725 - 1273.775.
Hope you find this useful.
