Can you please help me understand how NT is calculating this example of FLAT Rate Commissions using Market Replay.
I globally specified in NT->Control->Options-> Futures Replay a $2 flat rate.
The Strategy is trading YM, and I have specified NO COMMISSIONS for YM in NT->Tools->Instrument Manager.
When the strategy trades 1 YM Contract at a time, the commission NT calculates is what I expect, commission of $2.00 per order per side, or $4.00 per the entire order. Please see attachment rows 1-7
When the strategy trades 2 YM Contracts at a time, and NT must manage the execution of the trade using partial fills, the commission calculation does NOT look right to me. Please see the attachment rows 8-15.
The attachment was created using NT Reatime Strategy Performance Grid extract to Excel.
Rows 12-15 should have Commission of $2.00 (not $4, see red circles on attachment) since the trade execution quantity of the partial Fill is 1 contract, yet NT used $4.00 for the first Fill of each trade (row 12 & 14). Then NT added another $2.00 commission for the last partial Fill.
The result is the commission for both “partial fill trades” (Rows 12-15) is $6.00 each entire order, when it should add up to $4.00.
What Do I need to specify to NT, so that partial Filled order commissions add up to equal the correct $2.00 per order per side, or $4.00 per the entire order ?
Or can you please explain why NT is calculating Flat Rate Partial Fill commission this way, and what are the rules it follows for Flat Rate Partial Fill Commissions?
What would the Flat Rate Commissions look like if I traded 5 contracts that resulted in the execution of 4 partial Fills of Quantity=1,1,1,3… ?
Please let me know.
