A limit buy means he is willing to pay up to \$200 for 1 unit. Since there is one offer of 1 unit at \$100 that one will be bought out first followed by 1 unit at \$200. So only a total of \$300 of his money will be deducted.

data = bt.get('ETH-USD', start='2018-01-01')
s2 = bt.Strategy('s2',
[bt.algos.RunMonthly(),
bt.algos.SelectAll(),
bt.algos.CapitalFlow(1000),

The fair rate calculated in the above example is the rate to be used for fixed rate leg to yield 0 NPV. You would need to reconstruct the swap with the float leg as is but a fixed leg with fair rate from above. That should yield a 0 NPV for the swap.

Try casting, something like
c = as_coupon(cf)
if not c.__nonzero__():
print "principal redemption"
You can likewise attempt casting the cf to as_fixed_rate_coupon(cf) or to as_floating_rate_coupon(cf), and if they work, then access other useful info. Also, redemptions is another available inspector.

In R, the simplest way to brute force through a predefined number of portfolio combinations would be to simply iterate over them:
set.seed(42)
returns <- matrix(rnorm(200),40,5)
weights <- list(c(1,0,0,0,0),
c(0,1,0,0,0),
c(0,0,1,0,0),
c(0,0,0,1,0),
c(0,0,0,0,1))
conf <- 0.99
sapply(...

I will write some pseudocode.
N = 10 /* number of orders */
prices = [100, 108.01, 116.65, 125.99, 136.08, 146.97, 158.74, 171.45, 185.17, 200.0] /* these are the given prices */
ones = [1,1,1,1,1,1,1,1,1,1] /* N ones */
staircase = [0,1,2,3,4,5,6,7,8,9] /* starts at 0 and counts up by 1 until N-1 */
desired_avg_price = 135
avg_price_eqweighted = AVERAGE(...
