Finally I made it.

It took two days but that's not terribly bad for someone who knows zero
about Internet SW and protocols.

I feel I owe a summary. Comments in the code are explanatory.

Essentially, I now can access to the site with an automated libcurl login.

Thanks everyone for all hints, directions and for the time spent replying.

=======================================================
// Login Page
const string LoginPage = "https://us.etrade.com/e/t/user/login";

// Where the POST string must go
const string Login_fcc = "https://us.etrade.com/login.fcc";

const string stPostLogin =
"USER=myUSRid&PASSWORD=myPASSwd&TARGET=%2Fe%2Ft%2Fpfm%2Fportfolioview&Logon.x=0&Logon.y=0";

        // Not necessary, but it does not hurt:
        curl_easy_setopt(sessionA, CURLOPT_USERAGENT, UserAgent.c_str());

        // Essential! In the Header there is a Location: to follow:
        curl_easy_setopt(sessionA, CURLOPT_FOLLOWLOCATION, 1);

        // Regular stuff:
        curl_easy_setopt(sessionA, CURLOPT_COOKIEJAR, CookiesBag);
        curl_easy_setopt(sessionA, CURLOPT_COOKIEFILE, CookiesBag);
        curl_easy_setopt(sessionA, CURLOPT_WRITEHEADER, HeaderFile);

        // These are NOT necessary at all!
        // All works 100% fine without them. Any reason why I should keep
this?
        curl_easy_setopt(sessionA, CURLOPT_AUTOREFERER, 1);
        curl_easy_setopt(sessionA, CURLOPT_REFERER, LoginPage.c_str());

        // This is only for "visiting" the Login page and collecting the
        // necessary cookies prior to POST
        curl_easy_setopt(sessionA, CURLOPT_URL, LoginPage.c_str());
        result = curl_easy_perform(sessionA);

        // POST must go to a different page: login.fcc
        curl_easy_setopt(sessionA, CURLOPT_POSTFIELDS, stPostLogin.c_str());
        result = curl_easy_perform(sessionA); // then posting
