Manage positions from several strategies

[mcosta72]

Hi My Friends,

You guys probably wrote about this before but I couldn't find the right keyword. This is the situation:
I have 2 strategies (Unmanaged = true running at the same time over the same instrument, same account. Strategy A found a buy opportunity and executed 1 Buy Market, generating 2 other orders (Target and Stop). After 1 minute, Strategy B found a SELL opportunity and executed 1 Sell Market, generating 2 other orders (Target and Stop). Now my account position is flat and I have 4 unnecessary orders pending in my chart. I have all OCO setup in my OnExecution and OnPositionUpdate but since the SELL order came from Strategy B, Strategy A was not able to cancel Target and Stop (as programmed).
I tried to use Account.Position but it does not show me direction, only count.

Any help appreciated,

Well, there's your problem.

Don't do that.

If you want to do what you are doing, use 2 different accounts.

Hello mcosta72,

Your broker will have one position for each account and instrument. bltdavid is correct. You would need separate accounts.

Below is a link to a forum post where this is discussed.

Technically, same strategy (on same instrument same account) can be done -- if you code your strategy to such that you setup a trade lock mechanism. What I have done is that if Strat A wants to enter a trade (long or short, doesn't matter) it must first acquire the TradeLock -- if successful, it enters the trade. Along comes Strat B who wants to enter a trade, it tries to acquire the TradeLock but fails because Strat A has the lock, thus Strat B is denied trade entry.

The strategy code is designed so that the single TradeLock is a shared resource. Only 1 strategy at a time can trade, and that is whoever has acquired the TradeLock. The other strategy is simply denied entry and waits for its next setup.

I've used this with great success -- for ex, setup strat A to take longs only, and strat B to take shorts only -- and trading same instrument in same acct using two different instances of same strategy worked like a charm -- the TradeLock solution is what made this possible.

Thank you bltdavid and Chelsea,

@btldavid, The TradeLock idea is something that I would like to avoid, but I think it is impossible with the systems we have right now. I am going to allow the same direction orders be placed but I will definitely block opposite orders.

The next question is: Where in Account instance is stored the Long or Short Information? Account.Positions shows only quantity.

Does Anyone know anything about "Account" object?
Thanks

Hello mcosta72,

The Account class is not documented in NinjaTrader 7 so we cannot offer any support for its usage. I may suggest using Intellisense and using prints to see how you can use the Account object and Account.Positions collection. Prints similar to the following can help provide further direction.

foreach (Position pos in Account.Positions)
{
    Print(String.Format("Instrument: {0} MarketPosition: {1} Quantity: {2}", pos.Instrument.FullName, pos.MarketPosition, pos.Quantity));
}

If you have any additional questions involving documented NinjaScript, we will be happy to assist you further.
