Really, the entire subject is covered extensively in the book that you could have free except the people that run this board don’t allow me to tell you how to get it. Sorry. But there is a lot more science and simple math that goes into Mathematical trading than a bunch of guess work.
One pip on the aud/nzd cost or profits, $.07 per each .01 lots traded. From the center of the grid, centered between the historical limits, to the historical limits is 1400 pips. That means that .07 X 1400 = $98 or that if you had $100 plus $5.00 to cover the margin and the price never went beyond the historical limits, You could open a trade for .01 lots sells above center or buys below center and you would never margin. Lets also say that we will close each trade for a profit of 50 pips. This will give you a profit of $.07 X 50 or $3.50.
1400 / 50 = 28 ranges. If we open the trade when the price is at the far end of the range away from center and close 50 pips closer to center, we could have 28 ranges of 50 pips each. There would be one trade for .01 lots for each of the 28 ranges. It is just as easy to calculate the total draw down that would occur if the price of the aud/nzd went from center to the historical limits. (Remember that we calculated the center to the extreme at less than $100 for each .01 pips and each range closer to center would be cost $3.50 less than the one before it. I won’t bore you with how this is all calculated but it works like this. (28 X 29 / 2) X $3.50 = $1421 Plus the cost of the margin at 200:1 is $5.00 for each .01 lot traded. 28 ranges X $5 is $140
$1421 + $140 = $1561 Therefore, if you keep $1600 in the account and the price never goes beyond the historical limits you will never margin and each time the price travels through a range, you will make a profit of $3.50. Simple math, no opinion of any kind.
The same kind of logical reasoning is used to select which pair we trade, Which broker we use etc. There is some loss do to swap but profits are a lot more. You can hold the trade open longer than 50 pips if the trade is very old and the swap is large. (Note; swap for 1 year equals about 200 pips) The only danger is when the price goes beyond the historical limit. (The currency pair was chosen to minimize this effect.)
A max of 28 trades of .01 lots =.28 lots at .07 = $1.96 0r 2 bucks per pip beyond the historical limit. If you believe that the price would not likely go beyond 1000 pips over the historical limit and you put $2 X 1000 or an extra $2000 in the account as insurance then you have a pretty well protected program, If not actually the Holy Grail.
That is to say, the price of the aud/nzd could go anywhere between .9428 and 1.4230 with a balance of $3600 and your account would be perfectly safe. What’s more there are ways to generate profits from the insurance but that isn’t quite so automated so that the robot does all the thinking. This system has generated between 1 and 2.4 percent profit per month for the last 3 years without one single loss. (3000+ trades) It won’t work in the USA. FireStorm, the generator that I use to trade the insurance, (Profits of which is not included above as it averages about 6% per month) can give you a higher insurance level and extra profits.
No opinion, just math. We have already moved trading into the science world, let’s see what we can do next. If a computer can beat a grandmaster in chess, trading is child’s play. And that is the one and only opinion in this entire discourse.
