Heavy - I've been buying Sola all the way along in smaller increments. A couple times I placed orders through RBC Direct Investing, and the orders were filled on Alpha. Not understanding this I spoke with a Direct Investing Broker who let me know my order and volume would be reconciled with TSX at end of day. Sure enough it did. Its possible that the orders don't always reconcile. I just took the broker's comment to mean the exchanges are supposed to reconcile. Reading through Alpha's documentation it looks like because it is a secondary exchange to the primary TSX/V there are price parameters/thresholds that must be adhered to. I took this to mean that if a security traded xx% differently than the primary exchange there would be some form of filtering of the Alpha Trade. I put in an email to Alpha to see exactly how this works.
