                                                   Under-exposure due to multi-day Limit orders

I place multi-day Limit orders that are valid for 5 days (code below), and noticed I get only 48% exposure, even though I have only 5 positions
and a universe of S&P500 stocks (and the signals fire quite liberally) - my hold period is ~6 days.

It seems as though once 5 Buy Limit orders are fired and active, no more orders are triggered until the active orders are filled, and these orders may wait for 5 days and expire unfilled.
What makes this worse is if there are 3 positions and 2 active orders, no more orders are triggered.

Is there some way the system can fire all the orders signalled (could be 15) but fill only the first 5 and cancel the rest once the portfolio is full no remaining cash?
This would be expected in a live trading system.
- If not what's a work-around to get 100% exposure?

thanks
Kiran

Buy = r>ref(r,1) && uptrend;
//SetSimTiming(_Buy,_Close,-1);
SetSimTiming(_Buy,_Limit,0);
BuyPrice(r*(1-lt*brick/100), 5);

Sell = r<ref(r,1) || f;
//SetSimTiming(_Sell,_Close,-1);
SetSimTiming(_Sell,_Limit,0);
SellPrice(r*(1+lt*brick/200), 5);

Hi Kiran,

"This would be expected in a live trading system."

This needs to be implemented in a money management script. This is not a default behavior.
If you want the system to fill all positions no matter whether there are pending limit orders or not, edit your trading system, select "Settings -> Capital" then put "All Orders" next to "Pending Orders"

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
