I would like to create an algo which follows these rules (description in german),
for each one point:
p1 - last interest rate change of ECB a reduction https://www.quandl.com/data/BUNDESBANK/BBK01_SU0202-ECB-interest-rates-for-main-refinancing-operations-End-of-month
p2 - last Euro area HICP inflationrate under the value of the same month in the last year https://www.quandl.com/data/ECB/RTD_M_S0_N_P_C_OV_A-Euro-area-HICP-Overall-index-Annual-growth-rate
p3 - USD over the value from twelve month https://www.quandl.com/data/CURRFX/EURUSD-Currency-Exchange-Rates-EUR-vs-USD
pt - between 1th November and 30th April
pS = p1+p2+p3+pt
if pS = 3 to 4 points buy the DAX
else if pS = 2 points last signal
else if pS = 0 to 1 point sell the DAX
the calculation will be repeated every week
Don't know if these variables are best, but it was easier for me to describe it like this.
Thanks for any help!
