IB: Order rejected - reason: Invalid Price (201)

[junmachan]

When I submit a limit order for a FX currency from the Chart trader (same result from FX Pro) , I get such a failure if the limit price is slightly far (>20 PIPs) from the current price; it works as long as the limit price is very close to the current price. I have the FX sub pips support on.

If I make a same limit order (price, size, etc.) using FX Trader on IB, it works fine even if the limit price is way far. The thing that puzzles me is that both orders looks same on the TWS API tab, and the one created by NJ is rejected if I re-transimit.

Likely your price is 1/10 of a pip instead of 1/2 pip increment. Next update will ensure that prices in 1/10ths can't be submitted.

You are right. As long as the limit price has a 1/2 pip increment, it works fine.

So this probably also means the prices (stops, auto trails, etc.) generated by ATM need to have a 5-tick increment (i.e. 1/2 sub pip); I don't want to test that in a live trade

Your understanding is correct
