http://alphomegaew.com/ is the only MS plugin I know of, it can be trialed —
" Information. Return Policy: If you are not satisfied with the package within 10 days of the purchase, we will refund you." He's on holiday till Sep 6 so check with him after that date.
I don't use Alphomega, it's a massive addon having dozens of indicators, some trading methodology to apply with everything that's available plus instructions on how to set things up. Definitely not plug-n-play, it'll take several days (weeks) to test and become familiar with all the bells, whistles and kitchen sinks included.
The problem as Dcarrigan points out, is that EW based trading " comes with the knowledge of studying elliots wave ", not from software. EW software either provides dozens of 'alternate' counts — Elwave and/or will change the count as the Price progresses; while it's acceptable to use software counts as a guide — even for clarification or a second opinion sometimes, one has to rely on being able to asses count/label the Price Movement oneself, which includes revising one's own count when necessary.
