We have 8 indicators that we want to turn into just one technical indicator. For simplicity, we will give each indicator an equal weight of 12.5%. The way we will do this is normalizing the indicators that need normalization, multiplying them later by 12.5% (their weight), and finally, adding the pieces together. Here is a quick summary of what we will do:

**The Relative Strength Index**is already normalized and therefore no transformation is needed. We can simply multiply its values by 12.5%. As an example, if the RSI is showing a value of 100, then multiplying it by 12.5% will give a reading of 12.5 which is the maximum value of a weighted component in the Global Technical Index. This pushes the GTI up to approach a bearish zone.

`my_data[:, rsi_column] = my_data[:, rsi_column] * 0.125`

**The Stochastic Oscillator**is already normalized and therefore no transformation is needed. We can simply multiply its values by 12.5%. As an example, if the Stochastic is showing a value of 0, then multiplying it by 12.5% will give a reading of 0 which is the minimum value of a weighted component in the Global Technical Index. This pulls the GTI down to approach a bullish zone.

`my_data[:, stoch_column] = my_data[:, stoch_column] * 0.125`

**The Rate of Change Indicator**needs to be normalized with values between 0 and 100 and then, we can simply multiply its values by 12.5%. The normalization function is shown below.**The Momentum Indicator**needs to be normalized with values between 0 and 100 and then, we can simply multiply its values by 12.5%. The normalization function is shown below.**The Modified Fisher Transformation**needs to be normalized with values between 0 and 100 and then, we can simply multiply its values by 12.5%. The normalization function is shown below.**The MACI**is already normalized and therefore no transformation is needed. We can simply multiply its values by 12.5%.**The Normalized Index**is actually the function itself and can be seen as a High-Low index with a selected lookback period, therefore, we will simply multiply by 12.5% to get its weight.**The Astral Pattern**: As it is composed of values from -8 to +8 with -8 as a bullish timing signal and +8 as a bearish timing signal, we can simply create gradual values from 0 to 100 with 6.25 for every step. For example, -8 becomes 0, -3 becomes 31.25, 0 becomes 50, +7 becomes 93.75, and +8 becomes 100.

Let us quickly discuss how we normalize values between 0 and 100 before we proceed to understand more the GTI.

This great technique allows us to trap the values between 0 and 1 (or 0 and 100 if we wish to multiply by 100). The concept revolves around subtracting the minimum value in a certain lookback period from the current value and dividing by the maximum value in the same lookback period minus the minimum value (the same in the nominator).
