Signal Trailing stop loss not working as per code.

September 14th, 2012, 05:43 AM

I am using a trailing dollar stop loss by following exponential moving average. I have modified trailing stop loss so that I can set stop loss to the ema value at the end of each bar. So only if the price hits the ema value the position is exited.

However, I noticed that the stop loss is being hit even when the ema is still far away from the lowest point. Is there an error in the way I have coded this?

I have attached the image.

[IntrabarOrderGeneration = False]
inputs: PositionBasis( false ), EMA_Length ( 10 );

variables: Amount ( 0 );

Amount = Close - XAverage(Close, EMA_Length );

if PositionBasis then
SetStopPosition
else
SetStopShare ;

if MarketPosition = 1 then
setdollartrailing( Amount) ;

Then I don't understand why you use the trailing stop function. Just use a stop order at the value of the ema. Unless I am missing something.

Hi,

It may also depend on the instrument you trade.

You use:
setdollartrailing( Amount) ;

But are you sure that Amount as defined in your code is expressed in $?
For sure, it is expressed in price (I mean: the price displayed on the screen).
But, except for equities (?), this is not $.
In order to obtain $, you have to multiply it with the value of a full point in $.

Dear Nicolas,

How do I go about doing this? How do I modify the code to take this into account?

Dear Timot,

Thanks but I tired it. It just started trailing the close price. I am sure I have made a mistake. How can I rectify it?

I think you must multiply it by BigPointValue. Good suggestion by Nicolas11. But still my question stands.

First, I do not pretend that my answer closes the issue. There may be other problems in your code. I am not in position to review it. Read carefully the comments made by other futures.io (formerly BMT) members.

To implement my suggestion, just multiply Amount by the value of a full point in $.
You should know it for the instruments you trade.
Otherwise, you can use BigPointValue.
But I think it requires this field to be correctly input in QuoteManager (to be checked).
