When executing a PSC-Trader script to place a limit order with a value close to the current value, there is a problem that the market order is issued instead of the limit order.
(For example, in order to avoid slippage, if place a limit order at a value a few points away from last pric, It is ordered by market order. )
(In the case of FX, for example, if USDJPY bid109.211 ask109.213,
set the Buy Limit to 109.209 in PSC,
Executing the script will place a market order at 109.213. )
Anyway, place an limit order using PSC and PSC-Trader script to a value close to the current value, it will be a market order.
