Limit on periods of function

klaus · 2016-05-17T08:34:14+00:00

Does anybody know if there is a limit for the number of periods on a function like DEMA? Following program runs in backtest(one minute timeframe) but not live. I’m getting the message to increase preloadbars, which I have done thx Klaus defparam preloadbars =2000 once ldema=0 xDEMA = 1050 cDEMA = dema[xDEMA](close) DEMAcond = cDEMA < lDEMA lDEMA = cDEMA if demacond then buy 1 contracts at market else sell at market endif

I know someone who trade Hull moving average of 5000 periods in seconds timeframe.. So I guess it’s possible.

What is the error of live trading?

It says to increase Preloadbars, which was already done.

But anyhow, I changed program logic to circumvent the problem
