Hello JasonK,

thx, but it doesn't help me a lot,

i don't understand what a contract is, while back testing? according to that link it wold mean 1 contract = 1 us$ or am I wrong??

when I enter a default size 100.000 contracts, and there is a 100 pips stop loss, I got -100.000 US$ and it should be -1.000 US$, so i take default lot size 1.000 but that wold mean that 1 contract = 100 us$, is that right??

may be there is a faq or something like that which explains what esignal do while back testing with the contracts??

By default the Back Tester assumes that 1 point is equal to 1 US dollar however with futures contracts that may not be the case. So in the Default Lot Size you insert the value of 1 point for that future contract.
For example with the e-mini S&P 1 point (ie the change from 1100.00 to 1101.00) is 50 dollars so you use that value as the Default Lot Size. If you trade more than one contract then you multiple that value by the number of contracts traded and insert the result as the Default Lot Size. For 3 contracts you would insert 150 (ie 50x3)
Hope this helps

what do you mean with "e-mini S&P 1 point"??

For example there is a curse change from 130.00 to 131.00 this is a win of 100 pips, if I am long. That would mean, when i got with 100.000 € in that deal that i got a win of 1.000 €, am i wright?
so i tested a bit with the Default Lot Size and i only got that win of 1000 € if i buy 1000 contracts and that would mean that 1 contract is 100 €?

Can you please help me with the following, if i back test EUR/JPY there always stand a curs price in US$, is that normal? because i think there should stand JPY, if you want i can post a screen shot, and maybe it helps you understand what i exactly mean.
thank you,

What I mean is that every 1 point change of 1 e-mini S&P futures contract is equal to 50 US$. So if I go long 1 contract at 1100.00 and sell it at 1101.00 I gain 50 US$.
I don't trade Forex so you may want to ask your broker what the point value is for each Forex contract and use that as the Default Lot Size. Alternatively use 1 as the Default Lot Size and then apply the necessary math to the results returned by the back test.

You should use 100 000 as the default lot size.
This will give you $10 per pip movement on the USD/EUR.
For other currencies check on the trade platform for the pip value.
In the backtesting Strategy Analyser SETUP set the cost per trade to 30. Set the percentage returns to 0.

This should give you the correct answer in backtesting.

Hope it helps

The back tester runs through all the data that is in the chart. However in an efs you can define the period to be back tested. For an example of one way of doing this see the trade permission.efs attached to this post

hi,

i have a new question,

when i back test 60 min why does esignal only test the last 60 days and not the 120 days??

thank you,

Make sure that you have 120 days of data loaded in the chart. You do that through the Time Template

What symbol and efs are you using for the back test?
Alex

Alexis C. Montenegro

I use the MACD + Parabolic SAR study on eSignal 7.8

thank you,

Without knowing what symbol and efs you are using it is impossible to try and replicate the issue you are reporting.
As far as I can see here using I can run back tests across 120 days using for example the BTMovingAverage.efs which is in the BackTesting subfolder of Formulas.
