Creating Dollar Index

[dibDab]

can the dollar index be derived in Ninjascript using GBPUSD, EURUSD, AUDUSD, AUD/CAD, NZDUSD, USDCAD, USDCHF, USDJPY etc.?

Hello, thanks for writing in. The USDX is not a default instrument in the NinjaTrader database, so you would need to research which data provider will provide this index for charting and create a new instrument in the database.

ok thanks, I understand that you can pay to get the dollar index but wouldn't it be a cheaper/more convenient option to create your own indicator
with the option of adding your own symbols & weightings? (even better if we could plot a formula (or ratio) in NT8)

e.g. majors formula: USDEUR * USDGBP * USDAUD * USDNZD * USDCAD * USDCHF * USDJPY

e.g. emerging formula: USDCNH * USDZAR * USDNOK * USDSEK * USDRUB

and a similar exercise for any other index/ratio you wish to create

I'd be happy to make a start on a community indicator?

1. Find similar script to base it on e.g. https://ninjatraderecosystem.com/use...ownload/ratio/ (anyone know of something better for NT8?)

2. Keep it simple

3. Decide what parameters would work (without getting into parsing complex math formula)

e.g.

MSFT performance against S&P

parameter "Top" = MSFT

parameter "Bottom" = S&P 500

Dollar Index

parameter "Top" Top = 50.14348112 x USDEUR^0.576 x USDJPY^0.136 x USDGBP^-0.119 x USDCAD^0.091 x USDSEK^0.042 x USDCHF^0.036

(if USD is not the base value in the currency cross, the exponent weighting would be negative e.g. EURUSD^-0.576).

parameter "Bottom" = 1 (set to 1 if left blank)

evaluate then plot v = Top / Bottom

... something like that, all suggestions welcome!

Hi, I'd love to be able to use a community US Dollar indicator. I don't know how to code this, but I just read an 2015 article (see below) that has a formula that might work:

"The DJ FXCM US Dollar Index makes use of a more straightforward methodology based on 4 currencies in equal amounts – AUD, JPY, GBP, and EUR at 25% each."

Thoughts on this?

Hello dibDab,

I am not aware of any existing index or indicator with this specific logic. You could create a custom indicator for this.

Instruments can be added with AddDataSeries().

In BarsInProgress 0, the Value[0] plot would be set to Closes[1][0] * Closes[2][0] * Closes[3][0], etc.
