Pegged Orders

[ghost]

Is there support for pegged order types ? or support for limit orders that dynamically move with the best market quotes ?

[chronoxor]

Yes trailing orders are supported.

Trailing stop order - A trailing stop order is entered with a stop parameter
    that creates a moving or trailing activation price, hence the name. This parameter
    is entered as a percentage change or actual specific amount of rise (or fall) in the
    security price. Trailing stop sell orders are used to maximize and protect profit as
    a stock's price rises and limit losses when its price falls.
Trailing stop-limit order - A trailing stop-limit order is similar to a trailing
    stop order. Instead of selling at market price when triggered, the order becomes a limit
    order.

Makes sense, very nice. Thanks.

I think pegged orders are a bit different from trialing orders, no ?

I get a memory leak with the following example, using trailing stop limit sell:

CppTrader::Matching::MarketManager market;

// Prepare symbol & order book
const char name[8] = "test";
CppTrader::Matching::Symbol symbol{0, name};
market.AddSymbol(symbol);
market.AddOrderBook(symbol);

// Enable automatic matching
market.EnableMatching();

uint64_t order_id = 1;

// Add buy limit orders
market.AddOrder(CppTrader::Matching::Order::BuyLimit(order_id++, 0, 2521, 200));
market.AddOrder(CppTrader::Matching::Order::BuyLimit(order_id++, 0, 2519, 300));
market.AddOrder(CppTrader::Matching::Order::BuyLimit(order_id++, 0, 2515, 785));
market.AddOrder(CppTrader::Matching::Order::BuyLimit(order_id++, 0, 2510, 170));

// Add sell limit orders
market.AddOrder(CppTrader::Matching::Order::SellLimit(order_id++, 0, 2556, 300));
market.AddOrder(CppTrader::Matching::Order::SellLimit(order_id++, 0, 2555, 1000));
market.AddOrder(CppTrader::Matching::Order::SellLimit(order_id++, 0, 2535, 200));
market.AddOrder(CppTrader::Matching::Order::SellLimit(order_id++, 0, 2530, 150));

market.AddOrder(CppTrader::Matching::Order::TrailingSellStopLimit(9999, 0, 2500, 2520, 150, 1));
market.AddOrder(CppTrader::Matching::Order::BuyLimit(order_id++, 0, 2550, 500));

market.AddOrder(CppTrader::Matching::Order::SellLimit(order_id++, 0, 2529, 500));

Assertion failed: ((_allocated == 0) && "Memory leak detected! Allocated memory size must be zero!"), function clear, file allocator_pool.inl, line 338.

The leak seam to be caused because of the TrailingSellStopLimit and after the submission of the last SellLimit

Any suggestions on this ? Thank you
