# Possibly stupid question re lot sizing on Futures

46

Hi there

Wondering if somebody can help me regarding a possible stupid question regarding lot sizing? I have come across from spreadbetting and found MT5 as a mature platform that I can use for both backtesting and auto (algo) trading.

When back testing against Futures I use lots instead of £/\$ per point but the relationship between £ and lot sizes seem different for each Symbol.

An example:

Short UK100 (FTSE100) 28 lots, open at 6172, close at 5882, 290 pips = £8123 profit. (290 pips x £28 = £8120)

Short US30 (DJ30) 10 lots, open at 17217, close at 16243, 974 pips but £6753 profit (974 pips x £10 = £9740!!).

A lot size of UK100 seems to be £1 but US30 seems to be £0.69. I cant seem to find anything in the contract specification about this?

Sorry if this is a dumb question.

Answering my own question, I suspect this is currency. Guessing I need to alter my lot size dependent on currency rates!

use it to get tick value for MT4

`MarketInfo(Symbol(),MODE_TICKVALUE)`
