Error code 138 is a requote - see here and here

Calculated or unnormalized price cannot be applied. If there has not been the requested open price in the price thread or it has not been normalized according to the amount of digits after decimal point, the error 129 (ERR_INVALID_PRICE) will be generated. If the requested open price is fully out of date, the error 138 (ERR_REQUOTE) will be generated independently on the slippage parameter. If the requested price is out of date, but present in the thread, the order will be opened at the current price and only if the current price lies within the range of price+-slippage.

 Try RefreshRates() before doing your OrderSend

LastPrice+Step*Point*pt

is unlikely to be a valid price. Open a Buy at Ask and a Sell at Bid.

Good spot GumRai. I only looked as far as the first OrderSend.
