GetElliottStudy() Advanced GET Study Functions
Creates object which allows to get values of indicator Advanced GET Elliott Waves in EFS scripts. Elliott Waves, the "E" part of GET (Gann Elliott Trader), is one of the core studies of GET. The simplified Elliott Wave theory states that you will have a 5 wave sequence in a direction, some kind of corrective pattern (most of the time), and then a new 5 wave sequence in the opposite direction.
Syntax
GetElliottStudy( nNumBars , nPct4Overlap , nPct1LenOf3 , nMavg1 , nMavg2 , Alternate )
Parameters
| Parameter: | Description: |
| nNumBars | Number of Bars to calculate Elliott Waves
|
| nPct4Overlap | The percentage that Wave 4 can overlap Wave 1 before the Wave count is considered invalid and has to be recalculated. The default for any Futures contract is 17% (to account for slippage) and 0% for all other issues.
|
| nPct1LenOf3 | The maximum percent-level of the length of Wave 3 that the Wave 1 can be labeled. This percentage is important in the way the Wave 4 time channels and PTI are calculated. The default Wave 1-3 ratio is 50%. This means if you take the length of Wave 3, the Wave 1 could be labeled anywhere up to 1/2 the length of Wave 3. This does not mean that it will be labeled right at the 50% mark, but it could be labeled anywhere from the 1% up to the 50% level according to this percentage. If you decrease this number to 20%, this means that the Wave 1 has to be labeled somewhere between 1% and 20% of the length of Wave 3.
|
| nMavg1 | Number of periods to use for calculation of the first MA.
|
| nMavg2 | Number of periods to use for calculation of the second MA.
|
| Alternate | Boolean
