Thanks for the good suggestion.
If this ^^^ is true then the whole bonds thing is out of question if it can't be used as collateral for margin. Are you sure?You are going to have to provide liquid cash for your daily margin requirements regardless.
Why do you say "immaterial"? as in, the income from bonds is very little compared to earnings from high risk trading? (because that won't make sense to me as it's still some income regardless and unrelated to trading strategy).And if, as you suggest, you will be trading “high risk” products and strategies most of what you’ve been getting at is immaterial.
