Thanks for the tips wavemechanic! I'm not getting much success with switching any combination of the sell/short buy/cover combos (i.e. exrem(buy, short) to exrem(buy,sell) etc.) but I'll keep trying. On the other hand, I am trying to write my own stop using the http://www.amibroker.com/kb/2007/03/24/how-to-plot-a-trailing-stop-in-the-price-chart/ webpage.
A headscratcher now is that utilizing the code, i.e. Buy = cross(ma(c, 3), ma(c, 13)) Short = cross(ma(c, 13), ma(c, 3)) InTrade = Flip( Buy, Short ); sellstopline = IIf( InTrade, HighestSince( Buy, High ) * ( 1 - 0.01 * TrailingStop ), Null ); coverstopline = IIf( InTrade, LowestSince( Short, Low ) * ( 1 + 0.01 * TrailingStop ), Null ); Sell = Cross(sellstopLine,C); Cover = Cross(C,coverstopline); Buy=ExRem(Buy,Sell); Sell=ExRem(Sell,Buy); Short=ExRem(Short,Cover); Cover=ExRem(Cover,Short); This seems to work, except when running BackTest, I see some trades where it doesn't show that Trailing Stop worked, or if I specified a higher MaxLoss %, it shows the MaxLoss%, seemingly ignoring the trailing %. In detail, some trades have %'s stopped out that are much higher than the TrailingStop I specified (i.e. I specify trailing stop at 5% and in backtest I see Short(trail) or Long(trail) with >10% changes)...any ideas? And yeah, I know it's possible to have a gap up between days, so with all of those aside, I see instances on the same day where there are a good number of down bars (>7) between (long)entry and (maxloss, or none - no trailing!)exit and plenty of opportunity to trail out, but no signal. Any ideas? Is there something wrong with my code or is there something else? --- In [email protected], "wavemechanic" <[EMAIL PROTECTED]> wrote: > > Or maybe you were thinking about buy = cover = ... and short = sell = ... > ----- Original Message ----- > From: wavemechanic > To: [email protected] > Sent: Monday, January 07, 2008 10:19 PM > Subject: Re: [amibroker] Re: How to show Stops (ApplyStops) in Explore? > > > Looking more closely I would switch sell and short. applystop will stop buy with a sell not a short and stop a short with a cover not a buy.
