MaxTrades vs Tradesperbar

New comment
 
Noob question. I'm trying to get my EA to take multiple trades, 1 per pair at a time to avoid FIFO. Example - EURUSD - 1 trade / GBPUSD - 1 Trade / USDCHF - 1 trade. The EA I am utilizing has settings for both  MaxTrades/Tradesperbar . Can someone help me understand the difference, please. I don't want the EA to open up 4 trades in EURUSD and avoid trading on the other pairs, I would like for it to have one open trade per pair when possible, if that makes sense. Thanks.

Before sending a trading signal (or even better: as soon as a signal to open a position has been generated), it is necessary to check how many positions are open for this symbol.

An example of checking the number of positions by symbol - excluding Magic number:

Tactikill44: MaxTrades/Tradesperbar . Can someone help me understand the difference,
  1. Do you really expect an answer? There are no mind readers here and our crystal balls are cracked. Without the code we can only guess. Post the code or ask the owner.
  2. MaxTrades could be maximum count of trades on a symbol or all symbols.
  3. Tradesperbar seams self-evident but you would only have multiple signals if it trades using bar zero.
  4. If the EA only trades the current symbol you might be able to limit one trade per symbol using MaxTrades. Otherwise no idea without the code.
