Being able to optimize the timeframes is really cool, Lenar. Tradestation can't do that, NeoTicker can and now we know MetaTrader4, too.

I can tell you that the alternative platforms list discussed on our Yahoo group

http://finance.groups.yahoo.com/group/TheRumpledOne
(only about 20% of the members have migrated here so far) has narrowed to NeoTicker and MetaTrader4 I would say.

Thanks,

im not sure that understood you well. Please give me more details, Michal.

OK, in a nutshell:

- you need to subtract the costs of trading when you backtest

- in Forex, the principal cost of trading is the spread, i.e. the difference between the Bid and the Ask prices

- in EURUSD, the spread is typically 3 points

- is it possible to subtract the spread of 3 points from every closed out trade in backtest?

Strangely enough, you can't subtract spread in Tradestation. You can only subtract commissions or slippage in dollars, which is a workaround for USD-priced pairs, but that doesn't work for other pairs.

Example:

- EURUSD, 1 lot, spread 3 points = spread is $30 a trade

- GBPUSD, 1 lot, spread 4 points = spread is $40 a trade

- USDCHF, 1 lot, spread 4 points = spread is CHF 40 a trade

- EURGBP, 1 lot, spread 3 points = spread is GBP 30 a trade

etc.

The trick is to be able to denominate the spread in the price currency, which is not always USD.
