These numbers are a result of Monte Carlo analysis applied on our 10 random simulations. /pdfrw_0 100 0 R >> /Subtype /Link /Border [ 0 0 0 ] Provide details and share your research! /Contents 135 0 R /Rect [ 17.01000 693.69000 81.07000 685.69000 ] This test will give you an idea how the equity curve might look like if some trades are randomly skipped. f /Annots [ << /A << The uncertainty about the baseline models estimated effect size increases of the robustness test model obtains different point estimates and/or gets larger standard errors. /Rect [ 17.01000 693.69000 81.07000 685.69000 ] /A << Probability of change is a probability that any parameter changes its value. /ProcSet [ /Text /PDF /ImageI /ImageC /ImageB ] endobj >> /Annots [ << /Type /Page << /Subtype /Link /Border [ 0 0 0 ] Values at 90% confidence level mean that there is 10% chance that Net Profit, Drawdown etc. /S /URI /A << /Type /XObject >> The first row displays values of Net Profit, Maximum % Drawdown etc. will be worse than the confidence level values.
