[errorCode : INVALID_REQUEST] Order type STOP_LOSS_TAKE_PROFIT is not allowed for NewOrderReq

that's right, you cannot add SL and / or TP on a market order; still:

• you can place it and adjust SL / TP afterwards, using ProtoOAAmendOrderReq
• you can place pending orders with SL / TP

Market Range orders are also available, but that is another topic.

Yes l figured out that l can amend it afterwards. But that is not a very good proposition,  because between placing the order and amending it, the market may have moved significantly. It makes more sense for it to be implemented similarly to how it works in CAlgo desktop application. This current approach is unnecessarily cumbersome and in certain circumstances could expose the API trader unfavourably. Especially if one is trading the shorter timeframes such as M1 or M5 where the market can move swiftly during news windows.  We could lose money because of this. I am sure that is not Spotware's intentions.

The functionality to facilitate this is clearly there, so why not remove this poor aspect of the design. Leaving this poor design inplace is not in the best interest of OpenAPI traders. Hence l hope it would be corrected in the next release of the CTrader OpenAPI SDK

The situation is now more confusing to me. I removed the stoploss and takeprofit entries from the NewOrder request and the CTrader API server returns an error stating Stoploss cannot be None. I added the stoploss and takeprofit in pips and it returned the error below:-

description: "SL/TP in absolute values are allowed only for order types: [LIMIT, STOP, STOP_LIMIT]"

Please note that l have also tried it with absolute price value for Stoploss and Takeprofit and received the same error message above. As it stands, l am unable to open a new position due to this error. Please help!

SPOTWARE please comment on the above. 

My requirement is as follows:

1. I need to be able to set SL and TP for MARKET order type in the ProtoAONewOrderReq request. 
2. The value set for the SL or TP may be absolute price location or in pips relative to the entry price

Note:- This is the only risk free way to open a position and instantly protect it in turbulent market conditions. Also, this approach guarantees that the SL/TP are effectively anchored to the Bid and Ask prices at the point of entry. At any other time, the Bid and Ask price may be significantly misaligned to the entry price, thus causing the SL/TP to be ineffectively located and sometimes unfavorably located or rejected by the system. For us the current implementation is potentially too risky to use for real money trading.

SL / TP cannot be None / NULL for MarketOrder, their value needs to be DEFAULT => 0.0

you could use MarketRange order with relative SL / Relative TP instead

I would try MarketRange on monday when the market opens. I suspect that MarketRange is not on the list of ordertypes useable with ProtoOANewOrderReq. But l shall give it a go and see what happens. Nonetheless, thank you for your response.

// Order type ENUM
enum ProtoOAOrderType
{
    MARKET                = 1;
    LIMIT                 = 2;
    STOP                  = 3;
    STOP_LOSS_TAKE_PROFIT = 4;
    MARKET_RANGE          = 5;
    STOP_LIMIT            = 6;
}
