OrderModify only TakeProfit

[Yong Zheng]

I got sometimes Takeprofit modify error 130, when takeprofit go to negativ area. that means, takeprofit move buy order under orderopenprice, sell order move to upper. Then I got the error. I saw many other EA do also same, but they works without error. Why is it?

You can't move stops (or pending prices) closer to the market than the minimum (MODE_STOPLEVEL * _Point.)

modify #1 sell 0.01 EURUSD at 1.05100 sl: 0.00000 tp: 1.05143 ok

I saw this log from other ea. Why is that possible?

The takeprofit is above the opened price.

If I set the takeprofit in ordersend upper than open price it would failed.

The take profit may be above the opened price but is below the current price at the time.
