how to make my EA work with cryptocurrency?

John James Holmes 2021.09.13 19:24

Evening people. Second time posting and the feedback is incredible really pushing my learning along.

so my final issue with this EA is i backtest it yet it places no trades at all. Sometimes ill see it says "limit" trade and even then it wont be filled. Below is my code and any corrections and advic will be much appreciated.

try to use 1lot instead of 0.01? some brokers have minimal lotsize for crypto

Michael Charles Schefe 2021.09.14 05:03 #2

0.01 is very common minimum lotsize, and also lot step, however, i recommend that you check the symbol in MarketWatch for the lot step and the minimum and maximum lot allowed. From there you can use lotstep to equal a trade size that you can be confident that the broker will allow.

EDIT the reason that your Limit order is not being filled is because you are using the current bid and ask price. LIMIT and STOP orders can not be the current Bid and Ask prices.

if you want to use Bid and Ask prices, then use market orders OP_BUY or OP_SELL instead. You can search the site for difference between market orders and the other 2 types.

Need help understand stop [ARCHIVE] Any rookie question, Can an EA check
