For some reason I'm getting error 130 if SL or TP is below 80 points.
Ordersend() error 130 on IG broker for NAS100 STOPLOSS = iHigh(Symbol(),0,1)+_Point*1;

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.
MT4:NormalizeDouble - MQL5 programming forum
How to Normalize - Expert Advisors and Automated Trading - MQL5 programming forum - Prices you get from the terminal are already normalized.
- PIP, Point, or Tick are all different in general.
