One thing is ready made strategies, another is to develop your own.go to quantpedia. there are hundreds of tried and tested strategies that are commonly known, to ones used by hedge funds, that you can use as a starting point. choose a few that meet your criteria (ex timeframe) do your own backtesting, add your own filters, use your own data set or instruments. it doesn't have to be perfect, as nothing is , but you can very very easily get a market beating strategy that could involve just one indicator, and two instruments
As to ready-made you can also go to MyFxBook or sites who sell EA´s, many brokers have EA´s to use, some EA´s are even free to use. And we are back to the old days scam, pictures of a Ferrari next to a pool, bikinigirls, promising you get rich in no time. Today above has been replaced with stories about hedge funds in the attempt to lend credibility , where most hedge funds are in anyway not profitable.
This theme hasnt changed the past 15 years, the questions and answers are still same;
If you have a working strategy would you post it in public ?
What happens when 200 traders use the same signal ?
Would you store the code of a highly profitable strategy on an alien server ?
How long does it take till the strategy stop working - is it working right now ?
When was the strategy developed, and in which timeframe ?
Do you have sufficient data to backtest a strategy trading in the 30 minutes timeframe ?
Does it make any sense to backtest a strategy using data 3 years back ?
Why is it the longer back you optimize, the less trades per day you get ?
Which kind of strategies will you get if backtesting any strategy on any stock (hint long only due to 10 years bullish rally) ?
Is it possible to trade with profit one strategy, using data from one instrument ?
