Your baptism must meet these criteria in order to be true baptism.
>Be done in water
>Be done in the name of the Trinity (Father, Son, and Holy Spirit)
>Be done by way of full immersion
>Must be immersed thrice
Any baptism that is done counter to this that is not done by way of full immersion three times is not true baptism unless in an extreme case like when someone with a health risk is prevented from full immersion or when someone is on their deathbed or perhaps a few other circumstances when full immersion is impossible. If this is the case, then the recipient of baptism can be baptized by pouring thrice with water in the name of the Trinity. This is the exception. This is NOT the norm. And for the record, sprinkling is never ever true baptism even in extreme cases where full immersion cannot be done. At the very very least, there must be an action of pouring which, as noted above, in itself is only ever valid in extreme cases. When it's made the "norm" it is not true baptism.
Any baptism done by the criteria listed above is true baptism, even if done by heterodox groups, and may be accepted by Oikonomia. For this reason, Latin baptism (Roman Catholic, Anglican, Lutheran, and Reformed) as well as baptism done by various Anabaptist groups (Baptists, Pentecostals, Mennonites, Amish, Methodist) cannot be accepted as true baptism. This is because the Latins either sprinkle or pour and do not immerse even though baptism (coming from the Greek "baptizo") clearly means submersion into water and the early Church Fathers constantly attest to this fact; and the Anabaptist, while they do immerse, they immerse only once instead of thrice and thus do not have true baptism (see canon 95 of Trullo).
Those coming from the Monophysite sect in Egypt, Ethiopia, Syria, India, and Armenia have true baptism because their baptisms meet perfectly all the criteria above. They may be accepted into Christ's Church by Oikonomia by Chrismation.
Some Orthodox have accepted heretical baptisms by Oikonomia. This is counter to the true Orthodox faith and clearly a show of Satanic ecumenism seeping into some Orthodox circles.
So Latins, you do not have true baptism. Even if you did baptism right, like the Monophysites, it would still lack grace until you came into communion with the Orthodox Church by Chrismation.
