Method to ensure limit fill on ATM strategy

[zeller4]

Hello,

I'm using the SampleATMStrategy and have looked for ways to "guarantee" a fill of a limit order.

With a 50 tick chart:
When a candle "straddles" the entry price, the fill works with the first part.
However, sometimes the High[1] == entryPriceL and Low[0] == entryPriceL so those candles don't "straddle" the entry price and wouldn't necessarily give a filled condition.

I've tried using this but not sure the logic is right:

if ((High[0] > entryPriceL && Low[0] < entryPriceL)||
(High[1] >= entryPriceL && Low[1] <= entryPriceL)
)
{
longFilled = true;
}
if (longFilled)
AtmStrategyCreate(Cbi.Action.Buy, OrderType.Limit, entryPriceL, 0, TimeInForce.Day, orderId, "AtmStrategyTemplate", atmStrategyId);



Is there a better way to ensure a fill?
Thanks,
Kirk

Hi zeller4,

I understand what you are trying to do, however there really is no way of guaranteeing a fill with a limit order. You can guarantee the price with a limit order, or you can guarantee a fill (in most cases) with a market order. The price can jump around, gap up or down, so in general, I cannot comment on any way to "guarantee" a limit order fill.

I understand , that's why I put guarantee in "..."!

How about the use of Bid() and Ask() (with or without OnMarketData) so that if these "surround" my limit price, I can take the one that's close to the market?

Any sample code or snippets for that?

Hi zeller4,

You can access that with GetCurrenBid() or GetCurrentAsk() if you provider supports it.
Keep in mind this will only return the correct value in real time, live trading.
