How to determine US cents denominated future contract?

andrewyang95 commented 1 month ago

I am trying to compute future contract nominal size in US dollar, but I am unable to determine if this contract is US cents or US dollar denominated. Are there any fields we can use instead of hard-coding?

I checked contract details: ContractDetails(contract=Contract(secType='FUT', conId=665643542, symbol='YK', lastTradeDateOrContractMonth='20260814', multiplier='1000', exchange='CBOT', currency='USD', localSymbol='XKQ6', tradingClass='XK'), marketName='XK', minTick=0.00125, orderTypes='ACTIVETIM,AD,ADJUST,ALERT,ALGO,ALLOC,AVGCOST,BASKET,BENCHPX,COND,CONDORDER,DAY,DEACT,DEACTDIS,DEACTEOD,GAT,GTC,GTD,GTT,HID,ICE,IOC,LIT,LMT,LTH,MIT,MKT,MKTPROT,MTL,NGCOMB,NONALGO,OCA,PEGBENCH,RFQ,SCALE,SCALERST,SNAPMID,SNAPMKT,SNAPREL,STP,STPLMT,STPPROT,TRAIL,TRAILLIT,TRAILLMT,TRAILMIT,WHATIF', validExchanges='CBOT', priceMagnifier=100, underConId=13393285, longName='Mini Sized Soybean Futures', contractMonth='202608', industry='', category='', subcategory='', timeZoneId='US/Central', tradingHours=';20240728:1900-20240729:0745;20240729:0830-20240729:1320;20240729:1900-20240730:0745;20240730:0830-20240730:1320;20240730:1900-20240731:0745;20240731:0830-20240731:1320;20240731:1900-20240801:0745;20240801:0830-20240801:1320;20240801:1900-20240802:0745;20240802:0830-20240802:1320', liquidHours='20240728:CLOSED;20240729:0830-20240729:1320;20240730:0830-20240730:1320;20240731:0830-20240731:1320;20240801:0830-20240801:1320;20240802:0830-20240802:1320', evRule='', evMultiplier=0, mdSizeMultiplier=1, aggGroup=2147483647, underSymbol='YK', underSecType='IND', marketRuleIds='149', secIdList=[], realExpirationDate='20260814', lastTradeTime='12:01:00', stockType='', minSize=1.0, sizeIncrement=1.0, suggestedSizeIncrement=1.0, cusip='', ratings='', descAppend='', bondType='', couponType='', callable=False, putable=False, coupon=0, convertible=False, maturity='', issueDate='', nextOptionDate='', nextOptionType='', nextOptionPartial=False, notes='')

None of them contain the actual contract currency unit, which is US-cents, not US dollar.

the multiplier is multiplier='1000' isn't this what you are looking for?

andrewyang95 commented 1 month ago

Multiplier means different thing. To calculate nominal size, I use price x price_to_usd x multipler = 1079 x 0.01 x 1000 .

Since price is in USD cents, how can I programatically get price_to_usd for any future contract?

andrewyang95 commented 1 month ago

ok, I found priceMagnifier=100 hidden in the ContractDetails

gnzsnz commented 1 month ago

@mattsta I would like to suggest to move this issue as a discussion. as this is not a bug, been under discussions will help to give it more visibility.

mattsta commented 1 month ago

Yeah, this is actually a 3 step process I worked through myself recently. We should write an extra help page just about it.

Basically:

you need a Ticker() with minTick for the smallest increment you can trade, but that's not always enough because the price increment is defined per exchange.

The real answer is you need to:

fetch contract details
fetch marketRuleId details per listed exchange
also adjust via priceMagnifier if necessary
round your order limit prices based on the marketRuleId tick requirements per price range
- e.g. equity options trade on IBKR can trade $0.01 for all series because IBKR gives us access to the two NASDAQ exchanges which trade all equity options all in cents (plus internal IBKR-IBKR customer $0.01 trading) versus the normal "$0.01 under $3, $0.05 over $3" or "$0.05 under $3, $0.10 over $3"
- but things like index options always require the $0.05 -> $0.10 switchover at $3, so even though minTick on SPX options is $0.05, you can't trade $0.05 over $3

Basically:

mandatory $0.05 or $0.10 prices required

other equity options allow $0.01 for all prices on 3 exchanges but require rounding to $0.05 or $0.10 on regular exchanges (depending on if underlying is in the "penny pilot program" or not)

versus one with `priceMagnifier` too:

here, the official contract is quoted in 0.00025 but IBKR provides quotes and limit order prices 100x higher, so you are quoted in $0.025 and orders must be rounded to the "magnified" contract price instead.
