Which currency spreads don't you like? I find spreads in majors and even most crosses with my broker extremely appealing. Certainly a lot tighter than spreads in most stocks.
With liking I mean they allow me to algorithmically employ profitable strategies, both low latency and those with longer holding periods. I pay 0.1-0.3 pip spreads in eur and usdjpy pairs with an additional 9-20 usd dollars charged in commission per 1 million, traded. That is quite reasonable given I am not subject to corporate actions, short sell restrictions, pump and dump schemes, low liquidity as most in the stock market are. And I can express my macro views by entering into major fx pairs, emerging market currencies, and commodity currencies.
" Out there " is very vague. Just where is the average Joe going to find a very profitable algo and at what price ?
Nobody finds profitable strategies "out there", neither for sale, nor free. Strategies are found via research and development, testing, and implementation. I have at least in 15 years never come across any other short cuts.
Why would you post this here? If it worked, presuming you post stuff you yourself vetted and tested, would you not want to trade it yourself? Spreading the happiness and success amongst us all?
just to illustrate, that even if you go step by step and explain a method, most peoples egos prevent them from adopting the system. The systems are "out there", its much much harder for implementation secondary to all the hurdles.
