Error 130
SL = NormalizeDouble(SL, Digits);
- Floating point has infinite number of decimals, it's your not understanding floating point and that some numbers can't be represented exactly. (like 1/10.)
Double-precision floating-point format - Wikipedia, the free encyclopedia - Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.
- SL/TP (stops) need to be normalized to tick size (not Point) — code fails on metals. (On 5Digit Broker Stops are only allowed to be placed on full pip values. How to find out in mql? - MQL4 programming forum) and abide by the limits Requirements and Limitations in Making Trades - Appendixes - MQL4 Tutorial and that requires understanding floating point equality Can price != price ? - MQL4 programming forum
- Open price for pending orders need to be adjusted. On Currencies, Point == TickSize, so you will get the same answer, but it won't work on Metals. So do it right: Trailing Bar Entry EA - MQL4 programming forum or Bid/Ask: (No Need) to use NormalizeDouble in OrderSend - MQL4 programming forum
- Lot size must also be adjusted to a multiple of LotStep and check against min and max. If that is not a power of 1/10 then NormalizeDouble is wrong. Do it right.
- MathRound() and NormalizeDouble() are rounding in a different way. Make it explicit.

- "Sell Price" doesn't tell us whether you are trying to open a sell, sell limit or sell stop.
- You are using 3 PIP SL minus the spread, a 4 PIP TP (including the spread), and an open price of 3 PIP
You can't move stops (or pending prices) closer to the market than the minimum: MODE_STOPLEVEL * _Point or SymbolInfoInteger(SYMBOL_TRADE_STOPS_LEVEL).
Requirements and Limitations in Making Trades - Appendixes - MQL4 TutorialOn some ECN type brokers the value might be zero (broker doesn't know.) Use a minimum of two (2) PIPs.

You buy at the Ask and sell at the Bid.
-
Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using the 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 at 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 spread widen considerably at end of day (5 PM ET) ± 30 minutes. My GBPJPY (OANDA) shows average spread = 26 points, but average maximum spread = 134.

- When I tried pending orders, I saw similiar problems. It may be comparing TP/SL to current prices not pending price. You could try creating the order and then setting the stops.
- Humans can't watch the screen 24/7 so they use pending orders; EAs can, so no need for pending orders, have it wait until the market reaches the trigger price and just open an order.
