Indictor Index with customisable steps 1, 2, 3, 4 by being able to assign the net exposure under each steps. eg. step 1. Net long exposure of 100 AUD/USD step 2. Net long exposure of 200 AUD/USD step 3. Net long exposure of 300 AUD/USD step 4. Net long exposure of 400 AUD/USD Step -1. Net short exposure of 100 AUD/USD Step -2.
