RE: [amibroker] newbie have troubles with formula, AmiBroker Email List Archive

Hi Eric,

For both the ROC and EMA functions, you should specify a price or indicator array (e.g. the Close):

Buy= Cross ( ROC (C, 14), -10);

Sell=Cross ( EMA (C, 5), Close);

Also the ROC function returns a percentage as a fraction, so 10% would be 0.10. I’m not sure what you’re trying to do with the -10 which would be -1000%, but maybe you really meant to use -0.10.

Regards,

David

Subject: [amibroker] newbie have troubles with formula

hi, all. i am just trying to write simple trading ideas:

buy= cross ( roc (14), -10);

sell=cross ( ema (5), close);

there is always syntax error there. could i use different indicators as buy and sell signaling?

I run filter= roc (14) < -10 through australian data

but no single hit. can anyone help with this?

thanks for help.

eric
