I would like to automate my manual trading strategy. I detect occasionally a market drop on the S&P500 and buy a future and hold it a day. Most times such drop is before traders wait for a market annoucement like FED, ECB, tax plans. I would like to backtest my strategy. I use fast and slow Exponential Moving Average to detect in 14 days if there is a fast signal in a day (24 hrs). It works, but I find it strange that both EMA is alsways lower than the SP500 price. Is that for a reason?

Is there an algo to detect a spike in the SP500 (spy)?

Is there an signal to detect FED, ECB, tax plans?

Are there collegues here live trading futures? 

Are there collegues who like to work together on an algo?
