How can I cancel a trade when another is open and keep the open trade for a given duration?
I have written the code below that opens a buy and sell trade (a certain number of pips above and below the ask and bid price) at a specific time.
How can I close/cancel one immediately when the other is opened?
How can I close the opened trade if it's say X pips in profit or after a minute (depending on which condition is reached first)?
I'm a not too sure I've done the right thing in the code below and would really appreciate some help.
double spread = Ask-Bid;
extern datetime time;
extern int pipGap = 7;
extern int lotSize = 0.01;
extern int closeTimeInSeconds = 60;
int start() {
if (TimeCurrent() >= StrToTime(time)){
OrderSend(Symbol(),OP_BUYSTOP,lotSize, Ask + Point*pipGap, 0,0,0);
OrderSend(Symbol(),OP_SELLSTOP,lotSize, Bid - Point*pipGap, 0,0,0);
}
for(int pos = OrdersTotal()-1; pos >= 0 ; pos--) if (
OrderSelect(pos, SELECT_BY_POS)
){
int duration = TimeCurrent() - OrderOpenTime();
if (duration >= closeTimeInSeconds)
OrderClose( OrderTicket(), OrderLots(), OrderClosePrice(),
3*Point);
}
return(0);
}
Solution
AUTOMATED NEWS TRADING What you (@iGetIt ) are looking for is a rudimentary News Trading bot. Here's a diluted implementation for it.
In the more advanced stages, you will need to automatically download news and auto-trade base on the affected pairs, track volatility (to avoid swings), sync your PC time (Windows date/time is NOT accurate and news trading need to be synced to the millisecond level). Track your broker server response time, implement Trailing-StopLoss (for improved profit), implement slide-in-orders (multiple stop orders to catch huge spikes), calculate order-set profitability (to know when to close all the orders when price retrace), etc etc.
Anyway, here's a basic version that you can play with (based on the Bounty requirements):
- Opens buy + sell stop-orders at specific time.
- Configurable number of pips AWAY from current ask/bid.
- Implements OCO (One Cancels the Other).
- Closes executed trades with x-pip profit (aka TP level).
- Closes executed or outstanding stop-orders after x-seconds.
Visual: To show that it executes in time (this is Asian time, so liquidity is low, so +- a few seconds before price ticks).
Closing: It closes automatically based on the settings.
SOURCE CODE: And this is the complete MQL4 source-code for it.
(UPDATED 15May19 1045 GMT+8) to fix bug as reported in the closing of executed orders after TTL.
