In the CDN market Bull & Contra ETF's are not segregated between US & Canadian ETF's. The timing is differant although same exchange.
The present situation allows ETF searches in Canada that pick up US ETF on the Canadian market to appear. This cause a problem because the US and Canadian markets do not move at the same time. I get a Canadian based market signal, however the search is telling me to buy a US based ETF which is moving on a differant market signal. This causes the Canadian search to perform not as well as optimal, US based ETF should appear on he US market parameters not Canadian. I am sure this would be applicable todifferant countries as well. eg Australia etc.
