double BUYTakeProfitLVL = Bid+TakeProfit*Point()-Spread; //correct double BUYStopLossLVL = Bid-StopLoss*Point()-Spread; //correct double SELLTakeProfitLVL = Ask-TakeProfit*Point()+Spread; //correct double SELLStopLossLVL = Ask+StopLoss*Point()+Spread; //correctIncorrect.
You buy at the Ask and sell at the Bid. Pending Buy Stop orders become market orders when hit by the Ask.
-
Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using Ask±n, makes your SL shorter and your TP longer, by the spread. Don't you want the specified amount used in either direction?
-
Your sell order's TP/SL (or Buy Stop's/Buy Limit's entry) will be triggered when the Ask / OrderClosePrice reaches it. To trigger close to a specific Bid price, add the average spread.

The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools → Options (control+O) → charts → Show ask line.)
Most brokers with variable spreads widen considerably at end of day (5 PM ET) ± 30 minutes.
My GBPJPY shows average spread = 26 points, average maximum spread = 134.
My EURCHF shows average spread = 18 points, average maximum spread = 106.
(your broker will be similar).
Is it reasonable to have such a huge spreads (20 pip spreads) in EURCHF? - General - MQL5 programming forum (2022)

Thank you for the response.
Points 1 - 3, that did clear things up. got it mixed up. thanks a lot.
double BUYTakeProfitLVL = Ask+TakeProfit*Point(); double BUYStopLossLVL = Ask-StopLoss*Point(); double SELLTakeProfitLVL = Bid-TakeProfit*Point(); double SELLStopLossLVL = Bid+StopLoss*Point(); /* -----------changed below to above, works wonderfully :) double BUYTakeProfitLVL = Bid+TakeProfit*Point()-Spread; //correct double BUYStopLossLVL = Bid-StopLoss*Point()-Spread; //correct double SELLTakeProfitLVL = Ask-TakeProfit*Point()+Spread; //correct double SELLStopLossLVL = Ask+StopLoss*Point()+Spread; //correct */
Now it does open 2 positions when initially running, a SELL and a BUY. Correct TP and SL. But those positions are not what I thought it would do. It doesn't open a new position when receiving a signal. Might there be something wrong with reading the signal value?
I'll try to explain what im trying to accoplish. Im trying to make a scalper that uses the Bollinger Bands and Envelope indicators to scalp extremes. It looks as follows:
www tradingview com/x/pOXqoMoq/
I filled in the background of those indicators so that it is easier to see what i mean. I want the expert to open a short pending order, that moves up with the price, if price breaks the blue border. So that once price comes back down after breaking it to the up side, it scalps a few pips using a trailingstop and a small stoploss. I just cant wrap my head around how to code it, as im a trader. But im really eager to learn how to code. So if someone could please help me with this its much appreciated. I got the following code, but i got some hickups on how to write it correctly. I could really use some help. Thanks.

thanks for the quick response. what do you mean by ±n? sorry for my ignorance. did you mean it as n = tp/sl? I thought, as the lvls are showing correctly in the back test, it should be good?
I've been trying to create an Expert using the envelope indicator. Since adding automatic lot sizing it doesn't place anymore trades. Can someone send me in the general direction? As I'm not a programmer but willing to learn and dedicate a lot of time. It opens a buy and a sell and then it stops trading. please help. the notes at the bottom is what I want to add once im able to make this work so can be ignored.
Not related to your question, but I note that you are calling iBands/iEnvelopes in the OnTick() loop. This is not recommended - You should only call them once from OnInit() then reference the handle in OnTick().
